Bleeding in pregnancy

If you have any bleeding during your pregnancy, with or without pain, it’s very important to get it checked out.

Maternity care is still essential during the coronavirus pandemic and services are still running. If you have any concerns about your pregnancy call your GP, midwife, nearest early pregnancy unit or maternity unit.

Is it normal to bleed in early pregnancy (before 12 weeks)? 

It’s common to have light bleeding or ‘spotting’ without pain before 12 weeks. This isn’t often serious, but you should contact your doctor, midwife or Early Pregnancy Unit immediately to be checked, just in case.

Bleeding in pregnancy after 12 weeks is not common. Contact A&E or your hospital maternity unit immediately so you can be checked.

What can cause bleeding in early pregnancy?

Light bleeding or spotting can happen in the first trimester (first 12 weeks of pregnancy) for a few reasons.

Implantation bleeding

Implantation is when the fertilised egg (developing embryo) is embedding into the wall of the womb. This usually happens around the time your period would normally have been due. Some women have had implantation bleeding after 8 weeks of pregnancy.

An implantation bleed is very light bleeding (spotting) that is usually pinkish and sometimes brown. You may see it when you wipe after going to the toilet or in your underwear. It shouldn’t be enough to soak through pads or underwear. Usually it only lasts for a day or so, though for some women it can last a little longer.

Cervical changes 

Pregnancy hormones can cause changes to the cervix, which can sometimes cause bleeding. The cervix gets an increased blood supply and becomes softer. This can cause some bleeding after sex (known as post-coital bleeding).


Occasionally, vaginal bleeding can also be caused by an infection.

Bleeding and miscarriage

Bleeding can sometimes be a sign of something more serious. Try to remember that many women who have bleeding in early pregnancy (before 12 weeks) go on to have a successful pregnancy. Just make sure that your symptoms are checked. 


A miscarriage is when a pregnancy ends before 24 weeks.

Symptoms can include:

  • bleeding, especially bleeding that is bright red and and needs a pad
  • back or stomach pain or cramping.

Some women may experience a 'threatened miscarriage'. This is diagnosed where there is ongoing bleeding with or without pain but the woman is still pregnant.

Ectopic pregnancy

An ectopic pregnancy is when a fertilised egg implants outside the womb, usually in the fallopian tube. Symptoms can include:

  • bleeding
  • tummy pain on one side
  • pain in the tip of the shoulder
  • discomfort when peeing or pooing.

Molar pregnancy

A molar pregnancy is when a foetus doesn't form properly in the womb and a baby doesn't develop. Symptoms can include:

  • bleeding
  • severe morning sickness
  • an unusually swollen tummy.

What are the causes of bleeding in late pregnancy (after 24 weeks)?

Some women may experience a light bleed later on in their pregnancy. This is may not be from inside the womb, but from the cervix, for example, which can cause bleeding after sex. This may settle and doesn't necessarily mean there is a problem, but you should contact the hospital maternity unit immediately so you can be checked, just in case.

There are two more serious causes of bleeding in late pregnancy:

Low-lying placenta (placenta praevia) 

The area where the placenta is attached usually stretches upwards away from your cervix. A low lying placenta is when the placenta stays low in your womb, near to or covering your cervix. This may block the baby’s way out. In most cases, this would have been seen at one of your routine ultrasound scans and you will have an extra scan later in your pregnancy to see if the placenta has moved up.   

If the placenta is still low in your womb you may blead heavily during your pregnancy and your baby’s birth. This can put you and your baby at risk. If you have a low lying placenta and you have bleeding you may need emergency treatment – call 999.  

You’re more likely to need a caesarean section if you have a low-lying placenta.

Placental abruption (abruptio placentea)

This is a serious condition in which the placenta starts to come away from the womb wall. It usually causes extreme stomach pain which does not come and go like contractions. It may occur even if there is no bleeding.

Contact your hospital maternity unit immediately if you are bleeding in late pregnancy.

Find out more about placental abruption.

Rhesus negative

During your antenatal care your midwife will find out your blood group and whether you have rhesus positive or negative blood. Knowing which group you are in is important. If you have rhesus negative blood, but your partner has rhesus positive blood, your baby has a chance of having rhesus positive blood too. If this happens, your body might see your baby’s blood as different to yours and develop antibodies. These antibodies can pass across the placenta and attack your baby’s blood cells.

This won’t normally affect your first pregnancy, but it can be very serious in later pregnancies. Because of this, if you have rhesus negative blood your midwife will offer you an injection called anti-D during your pregnancy to protect your baby.

If you have any bleeding or trauma to your bump (for example, if you fall over) contact your midwife or hospital maternity unit immediately. You may need to be checked and possibly have another injection of anti-D.

Talk to your midwife if you have any questions about your and your baby’s blood type.

Where should I seek help for bleeding in pregnancy?

Any bleeding in pregnancy should be investigated even if you are not experiencing any other symptoms. It is important to make contact with a health professional to be seen as soon as possible.

Before 12 weeks pregnant

If you feel generally well and the bleeding is not heavy, then you can call your GP or midwife (if you have one yet) for an appointment who can then assess if they need to refer to the local Early Pregnancy Unit. Sometimes, you can self-refer to a local Early Pregnancy Unit depending on your history and where you live. If you call your local GP surgery they should be able to advise you. 

You can also call NHS 111 if you feel you need urgent medical help but it is not an emergency.

Go to your local A&E if you are experiencing bleeding and:

  • it is during the night or at the weekend when a GP is unavailable
  • the bleeding is heavy
  • the pain is severe
  • you feel generally unwell

After 12 weeks pregnant

Go to your local A&E or contact the hospital maternity unit immediately so you can be checked, just in case.

What to expect if you need to go to the Early Pregnancy Unit?

When you go to the Early Pregnancy Unit you may wish to bring someone with you for support.

Firstly, you’ll be asked about:

  • your symptoms
  • your medical history
  • any previous pregnancies
  • the date that your last period started (so they can estimate how many weeks pregnant you may be).

Then, they may ask you to provide a urine sample to confirm that you are pregnant, or you may have an ultrasound scan.

They may also do an internal scan, where a small probe is inserted through your vagina to get a clearer picture. This is helpful if you are very early on in your pregnancy. It is not possible to do an abdominal scan as the pregnancy sac is tucked deep inside the uterus, in the pelvis, so a vaginal scan is the only option this early in the pregnancy.

Ultrasound scans are safe to have and do not carry any risk of causing a miscarriage.

It’s unlikely that they will be able to see a heartbeat if you’re not around 6-7 weeks pregnant yet. Instead, they will be checking the size of the pregnancy sac and that it is in the womb. This helps to rule out an ectopic pregnancy.

It’s usually possible to see the baby’s heartbeat from about 7 weeks. Sometimes they may need to invite you back for another scan about 1-2 weeks after your first one if:

  • they want to check the baby’s growth
  • they could not get a good enough picture during the first scan
  • your bleeding or other symptom continue.

Other tests and examinations you may have

A speculum and/or vaginal examination

This involves a small instrument covered in gel being inserted into the vagina. This allows the doctor to check the neck of the womb to see if there is any obvious cause for the bleeding. It isn’t painful, but it can sometimes be a little uncomfortable.

Vaginal swab

This involves inserting a swab (which looks like a long cotton bud into the vaginal to collect some cells. This is to check for infections, such as chlamydia. The swab is safe to do and not painful.

A blood test

This is done to check your pregnancy hormone level (hCG). If this is under 5 IU/L then this indicates that you are not pregnant.

If it is above 5 IU/L they will expecting it to double about every 2-3 days, so they may ask you to come back to the unit for another blood test a few days later to see if the level is rising or falling.

Depending on the results of these tests, they will plan with you what will happen next. It can be a bit overwhelming when you get a lot of information at once, especially at stressful times, so feel free to ask as many questions as you need to make sure you understand what is happening and what to expect. They should also give you some written information to take away with you and a contact number to call in case you have further questions or need advice when you get home.

Bleeding in pregnancy when you have had a previous miscarriage

If you have bleeding in your current pregnancy after one or more previous miscarriages, recent research has shown that progesterone can be beneficial. This research was published in 2019 and showed that the more previous miscarriages you had, the greater the benefit from progesterone treatment.

Progesterone is a hormone that helps thicken the lining of the womb and the mother’s body to accept the growing baby. It is given as pessaries (tablets) and taken twice daily in the vagina (like inserting a tampon).

The study that showed that progesterone can be an effective treatment was a large, multi-centre, randomised controlled trial, which is the gold standard of research trials.

4,153 women with early pregnancy bleeding from 48 hospitals across the UK participated in the study. Around half the women were given vaginal progesterone tablets and the other half were given placebo (dummy) tablets. The findings were:

  • For women with no previous miscarriages: the live birth rate was 74% (824/1111) in the progesterone group and 75% (840/1127) in the placebo group, i.e no benefit.
  • For women who have had 1 to 2 previous miscarriages: the live birth rate was 76% (591/777) in the progesterone group and 72% (534/738) in the placebo group, i.e some benefit.
  • For women who have had three or more previous miscarriages: the live birth rate was 72% (98/137) in the progesterone group and 57% (85/148) in the placebo group, ie substantial benefit.

The study did not find any safety concern from progesterone treatment.

Talk to your doctor

If you have early pregnancy bleeding and a history of a previous miscarriage, progesterone treatment can be of benefit. As this research is relatively recent, your doctor may not have heard of it, so please discuss this treatment with your GP or the doctors at your local Early Pregnancy Unit. If necessary, show them this information or or download this leaflet and take it with you.

      Hi Deirdre, Thank you for your comment.
      We are so sorry to hear about what you have been going through, this must be a very difficult time for you and your partner. It is very difficult to diagnose this as a miscarriage and we would urge you to seek medical advise as soon as possible. A miscarriage can happened even when a heartbeat has been seen on scan and this can never be predicted. Have you had any investigations into recurrent miscarriage? If you are under the IVF clinic then it would be advisable to get in touch with them and speak to the Dr who is looking after you who can probably give you more accurate information. When using a donor egg there will always be a probability of risk and different success rates, this is why speaking to the fertility specialist may be a good option for you. We hope that you have managed to seek medical advise today and that you are being looked after well. Take Care, Tommy's Midwives x

      Hi i had a misscarriage in july i was 13 weeks +5 days, little bleeding on the tuesday scanned at the epau said all was fine, on the thursday evening i had a complete misscarriage whilst at work. I am now 5 weeks + 5 days & today i have noticed then when i wipe after a wee ther is a pinky/brown discharge on the tissue please advise as i really dont want to go back to the epau i went before & have booked a private scan in 8 days time . Is the discharge anything to be really concerend about, i am seeing my gp in 4 days time & my midwife in 2 weeks to book in . Please advise me. Thankyou.

    • By Midwife @Tommys on 27 Sep 2018 - 10:37

      Hi Lesley, Thank you for your comment.
      We are so sorry to hear about your miscarriage back in July, this must of been a very difficult time for you. Please be reassured that light pink brown spotting in early pregnancy can be very normal, it could be the remains of an implantation bleed. If you are concerned and don't want to wait until your private scan, you can always contact your GP who should be able to refer you for an early reassurance scan. This should be in the EPAU and it is understandable why you don't want to go back there but this is an option for you if you feel that this would be of help. Try and take it easy and if you have any heavy red bleeding or abdominal then please seek medical advice. Take Care, Tommy's Midwives x

    • By Briana (not verified) on 4 Sep 2018 - 11:59

      Hi. I am 4 weeks and 5 days pregnant. Started having brown spotting 3 days prior my period. Tested positive on that day.
      However on day 9, I'm still seeing brown and sometimes fresh blood when i wipe. I am worried as it is my first pregnancy.
      Is it normal to have spotting for such a long time?

      Thanks for your help.

    • By Marisa (not verified) on 15 Jul 2018 - 19:28

      I m spotting when i wipe for 2 1/2 days now. 5 1/2 weeks pregnant and i go to work tomorrow. Im worried it can cause problems but my dr said not to worry. I miscarried 1 yr ago so im just scared

    • By Midwife @Tommys on 18 Jul 2018 - 12:13

      Hi Marisa
      If you have been reviewed by your doctor, then hopefully he/she has booked you in for another review soon?
      Spotting in early pregnancy can be normal- but being reviewed is sensible- as you have already done.
      If the type of work you is too much, then your doctor can advise you. So perhaps it might be best to be seen again as soon as you can to get his/her advice.
      All the best

    • By Beth (not verified) on 7 Jul 2018 - 01:46

      Im really hoping for an immediate or quick response. I’m 7.5 weeks pregnant (I think, from a due date calculator site) and went on vacation a few days after we took a pregnancy test. I started bleeding 6 days ago and it hasn’t stopped. I need to wear a pad and change it 2-3x a day. It’s like a very light period. I don’t think I’m actively miscarrying, as I’ve heard that’s much more intense and lots more blood. I have had 3-4 episodes of mild cramping and that’s it.

      I’m wondering if I should go see someone while I’m on vacation (not sure about insurance and costs on that). I was given the impression to wait it out and go see a midwife when I return home....which would be in 4 or 5 days. I guess that’s not hat far away, but as time has gone on I’m feeling guilty and questioning not getting checked out. Thank you! Bethany

    • By Midwife @Tommys on 9 Jul 2018 - 15:07

      Hi Beth,
      I would assume that you have made a decision as to whether to be checked out or not. We are not here at the weekend and are not able to respond urgently.
      It is possible that you have been having a miscarriage although I couldn't confirm that without tests. Pain/cramping and bleeding together is a symptom. Your decision depends on where you are and how heavily you are bleeding. Please don't hesitate to contact us if you need support when you are back from your holiday.

    • By Ellie (not verified) on 4 Jul 2018 - 18:22

      I had an early scan after having miscarrying my last pregnancy. I am currently 9week and 2days. The scan was a TV ultrasound at the time there was no pain. Woke up this morning with spotting and 2 small clots. Is this normal to spot after a TV scan?

    • By Midwife @Tommys on 5 Jul 2018 - 14:17

      Hi Ellie, Thank you for your comment.

      Some women can experience some spotting after a TV scan but as you have past 2 clots then it is advisable that you seek medical advice, you have had no red bleeding or abdominal pain and this is reassuring but just because of the clots please get checked over for your reassurance. You can call the GP or early pregnancy unit if this is available. Take Care, Tommy's Midwives x

    • By Sarah (not verified) on 3 Jul 2018 - 21:24

      Hi, I'm 42 and 20 weeks pregnant and since the beginning of my pregnancy once a month I've been getting brown discharge only for one day then it goes and I have really mold period pain, but only lasts a couple of hours. But this evening when I went to the loo I wiped and had brown blood, didn't look like the last times I had it, again with mild pains or more like an ache.
      I had my 20 week scan yesterday and all day and now I can feel the baby move.
      I'm quite worried as to what to do.

    • By Midwife @Tommys on 5 Jul 2018 - 13:38

      Hi Sarah, Thank you for your comment.

      It is reassuring that you have had your 20 week scan and that all was well, but if you are getting these pains and brown loss often, then we would advise that you call your local maternity unit to be seen. It could be that you may have erosions on the cervix that can bleed due to the increase blood supply but it is always better to get checked over and feel reassured. Hope this helps, Take Care, Tommy's Midwives x

    • By Virgie (not verified) on 15 Jun 2018 - 15:33

      Hi I'm 9 weeks and 4 days preggy and I've been bleeding for two weeks I used
      two pantyliners a day and every time I pee there is brown blood. At 8 weeks it was bright red but after 3 days it becomes brown and so on. I did and ultrasound and the baby has a strong heart beat and no complications but why am still bleeding today? I'm scared i might miscarried.

    • By Midwife @Tommys on 18 Jun 2018 - 14:45

      Hi Virgie, How long ago did you have the scan? If it was two weeks ago and you have continued to bleed it may be sensible to have another scan. However, we also know that women can have some bleeding as you describe and go on to have a normal pregnancy with a healthy baby.

    • By Clara Mkandawire (not verified) on 1 Jun 2018 - 10:07

      I Am 20 Weeks Pregnant But Am Still Bleeding Every Month. What Is The Problem Pls Help.

    • By Midwife @Tommys on 1 Jun 2018 - 12:14

      Hi Clara,
      Occasionally, for some women, some bleeding in their pregnancy when their period would have been due can happen. However as with any bleeding in pregnancy we would always advise you to call your maternity unit to be reviewed. At 20 weeks you should also have had a scan recently or have one booked soon, if not then do contact your midwife as soon as possible to arrange this.
      Best wishes

      I am 42 and I have two children and this is my third pregnancy. I haven't seen spot bleeding during my previous pregnancies. Today I am eight weeks pregnant and I have been seeing spot bleeding for the three days hitherto. I visited gynecologist two weeks ago and he told me by blood and urine test my pregnancy is ok and my pregnancy is not out of womb. Then what is the cause of the bleeding? please, I need your immediate advise. Thank you very much!!!

    • By Midwife @Tommys on 29 May 2018 - 15:15

      Hi Helen
      Sometimes bleeding in early pregnancy cannot be explained. Bleeding at any gestation of pregnancy should always be investigated as you have done, so you have done the right thing by getting checked.
      It would be sensible for you to be scanned if you have another episode of bleeding to ensure that all is ok with the pregnancy. Your local early pregnancy assessment unit can review you and do the scan if they think it is necessary. Here is a link to our page on bleeding in pregnancy, you might find it useful.
      I wish you all the best for the future

    • By Midwife @Tommys on 11 May 2018 - 10:09

      I am sorry to hear that you are experiencing a worrying time at the moment. It is great to hear that you have been seen at the hospital and everything was ok however you say that the bleeding is on going and that you have a new symptom which is the cramps. It is great that you have not had any clots however it sounds like you should contact the hospital again to be reviewed. I know it is natural to think the worse, however it does not necessarily need that you are having a miscarriage.
      I hope this helps and wish you all the best.

      Bleeding in pregnancy is a worry but just to let you know I had heavy bleeding with large blood clots in my first pregnancy three times during the first trimester but after that it stopped. They never found out exactly why but each time I would go to A&E or early pregnancy unit and they would scan me to check everything ok. Advice would be to keep in contact with hospital, go in with any changes, and try to rest and keep on top of your iron either through food or Floridix and Spatone. I hope everything is ok x

      I had some bleeding and stomach pains. I did call the MAU however they just said to keep an eye on it. How do I know there's no problems with the baby? I'm 14 weeks!


    • By Midwife @Tommys on 26 Apr 2018 - 12:23

      Hi Claire,
      We would advice that you call your local maternity unit again as you are bleeding and experiencing abdominal pain, they may want to scan you to see if there is any cause for the bleeding. You can also call your GP as well who will be able to refer you. Hope this helps, take care, Tommy's Midwives x

      I'm 8 weeks and 4 days pregnant. Yesterday I had some spotting which then stopped. And then today whenever I wipe there is some blood and I've got some aching in my back. I have endometriosis and I had an ectopic pregnancy last year. Do you think this could be happening again

    • By Midwife @Tommys on 16 Apr 2018 - 10:35

      Hi Kelly, I am sorry that I was not able to reply on Saturday. At Tommy's we work Monday to Friday 9-5pm. I hope that you have been able to seek advice from the NHS over the weekend. With any bleeding at 9 weeks we would advise that you are seen and with a history of ectopic pregnancy you should be seen promptly. Please let us know if we can support you further and best wishes.
