How will I know when I am pregnant?

How do you know when you're pregnant? If you've been trying for a baby, there are a few ways to find out whether you're expecting.

Early pregnancy symptoms

If you notice one or more of these symptoms, it might be an early sign of pregnancy and a good idea to take a pregnancy test.

•      Late period
•      Extreme tiredness
•      Need to wee more often
•      Nausea
•      A metallic taste in your mouth
•      Sensitivity to smells
•      Tender or sore breasts.

How do pregnancy tests work?

Pregnancy tests work by detecting one of the key early signs of pregnancy: a hormone called human chorionic gonadotrophin (hCG). This hormone is only made when a woman is pregnant.

Traces of hCG can be found in the urine from three to four days after implantation, but the concentration needs to continue to build up to a level at which the test can detect it and give a positive result. The best time to take a pregnancy test is from the day that the period is missed. 

Where can I get a pregnancy test?

GP pregnancy test

These tests are either free or a small fee is charged.

You’ll need to take a sample of your urine in a clean container (you can get sample pots from your GP’s surgery). The best time to collect a urine sample is first thing in the morning. This is because levels of hCG will have built up overnight.

If the urine sample is tested on the spot, you probably will be given the result after just a few minutes. You may have to wait up to a few days for the pregnancy test results though.

Home pregnancy test

These tests are available to buy from chemists or supermarkets and enable you to find out if you are pregnant in private after a few minutes.

The tests are considered to be quite accurate, although it is essential that you follow the manufacturer’s instructions carefully.

Choose a kit that you think will be easy for you to use and make sure that you understand what mark or symbol will appear if the test is positive.

Find out more about taking a pregnancy test.

How accurate is the pregnancy test?

It is important to know that whilst a positive result is likely to be accurate, a negative result may be misleading. Some women have a negative result and test again a week later to find that it is positive.

This is due to the levels of pregnancy hormone gradually building up to a level at which they can be detected. If you test yourself very early on and you have a negative result, you should carry out another test in 2-3 days’ time if you have still not had a period.

If you continue to get negative results and still no period, you should consult your doctor.

What should I do if I am pregnant?

Once you get a positive pregnancy test, make an appointment to see your doctor or a midwife.

Tell the doctor’s surgery that you have had a positive pregnancy test result as you might need a longer appointment.

Your doctor’s surgery should be able to advise you of their procedure.

    Hi I've been on the contraceptive pill for 8 years and stopped taking a couple of months ago. My first period was regular like normal on the 28 day cycle. The one after that was 16 days late I then can on for 4 days. Then 4 days later had blood when wiping after a wee. I have had unprotected sex within this 2 months. I wondered how long the pill stays in the system for? I've had cramping after my period and have been drinking more fluid Especially through the night .

    Hi Don't worry, It can take a while for your cycle to settle down. Take a look at our top tips for conception and ensure you are enjoying a healthy lifestyle. If you are concerned that you are excessively thirsty even at night, you may like to discuss this with your doctor

    Hi, myself and my partner have been trying to concive for a while now. I had an eptopic pregnancy in January where lost my left tube. We have started trying again but my cycles are all over the place normally ranging from 33 days to 37 days.
    This cycle my period started on the 11th of July, I have been trying to track my ovulation but the results where difficult to determine when I, or if i ovulated. .I finally got a very strong ovulation lines for 2 days on the 30th day of my cycle the 9th and the 10th of August ( can it be possible to ovulate that late? ) myself and my partner had sex on the 8th and the 10th of August.
    I've been having quite a lot of cramps and my boobs feel funny. .I have been feeling a bit run down. I did a test yesterday and was negative. I know it will be much more difficult for me to get pregnant with only having one tube. It's just getting me down. I'm due to see the hospital next month about secondary infertility. Just wondered if I might of tested to early and there might be a glimmer of hope.

  • By Midwife @Tommys on 21 Aug 2017 - 16:02

    Hi, and thanks for your question. Yes it is possible to ovulate as late as that and it accounts for why your periods are so variable at the moment. I would therefore do a pregnancy test after the 24th August which will be 2 weeks after ovulation. In the meantime have a look at our tips for conception and the best ways to get you into prime condition for a pregnancy. Best wishes

    Hi I had a period on 21st july 2017 came of on 27th july ovulation happened 2nd August till 8th August period is every 31 days always been same had sex on 3rd and 4th August no contraception used at all when should I test and whats best pregnancy test to use? Feel nauseous all time stomach bloating back pains tired all time not what I get with my periods so could this be sign of pregnancy?

  • By Midwife @Tommys on 16 Aug 2017 - 09:07

    Hi there. It is possible that you are pregnant if you had unprotected sex at the start of august. It would be sensible to wait at least another week before testing with a pregnancy test so that the HCG levels have time to build up in your body - this is detected in the urine via a pregnancy test. The best time to take a pregnancy test is first thing in the morning, when the hcg levels are likely to be at their highest at the first void of the day. There are no pregnancy tests "better" than any other. So choose a brand that you are comfortable with using and a cost that feels acceptable to you. Nausea, bloating, back pains and triredness can be symptoms of pregnancy, but they could also be unrelated. If you do not have a positive pregnancy test and these symptoms persist, it might be sensible to go to your GP and discuss your symptoms there. They might find it appropriate to send you for a Gynae review if you are not pregnant. Please do feel free to get in touch if you have any further concerns

    I'm late on, was due on 2 days ago. I'm wanting to do a test but scared it will be negative as I've read your period can be up to 6 days late and that be normal. I've been having all tehhe cramps I'd expect just before I'm due on but nothing as of yet?!? What should I do?!?

  • By Midwife @Tommys on 8 Aug 2017 - 09:05

    Hi Emilia. It is a little too early to do a pregnancy test just yet, so it would be sensible to wait another week (i know that will feel like a long time) to ensure that a pregnancy test is result is more likely to be an accurate positive or negative result.
    Cramps are common just before and during a menstrual cycle and can be normal in early pregnancy when implantation occurs, so do your best to wait and then test. I hope you get the result that you want!

    I came on my pd on the 30th jun and ended on wed 5th July. I then come back on 15th July for 2days then stopped. my period is normally at the end of every month but i have not come on. I took a pregnancy test on 29th but it was negative. Help

  • By Midwife @Tommys on 31 Jul 2017 - 14:30

    It is possible that you may have done the test too soon. If there is a possibility that you could be pregnant I would suggest doing another test in a few days. Or it may be that your periods are a little irregular and you will have a period in the next week or two. If you are wanting to become pregnant remember to start taking folic acid and look at your diet and exercise to optimise your health in preparation for a pregnancy. Good luck x

  • By Midwife @Tommys on 20 Jul 2017 - 11:48

    Hi Grace,
    Sometimes it is very difficult to distinguish between pre period symptoms and early pregnancy symptoms. If you are still having these symptoms as well as a missed period i would advise you to go and see your GP. Also sometimes tests can come back negative if they are done too soon. Please contact us on 0800 0147 800 if you would like to discuss further.
    Best Wishes,
    Tommy's Midwife.

  • By Midwife @Tommys on 24 Jul 2017 - 12:49

    Hi. If you are getting repeated negative pregnancy tests it is unlikely that you are pregnant. I would suggest that you make an appointment to see your doctor to discuss your symptoms.

  • By Midwife @Tommys on 18 Jul 2017 - 13:45

    Hi, Thank you for your comment. You may be showing signs of being pregnant or you may have a urine infection which is causing the nausea and wanting to pass urine often. If you have been having unprotected sex and your period is late then there may be a possibility of being pregnant. What you need to do next is take a pregnancy test and see if it is positive. If you are pregnant then we would advice that you see your GP so that they can advice you further on what happens next. If you aren't pregnant it would still be advisable to see your GP just to rule out any urine infection. Hope this helps. Tommy's Midwives x

    I've been on the pill that stops my period however the last months I've been forgetting to take them. I missed two days then took on ethe missed another two days, then started again. I have unprotected sex during these times. Recently I've been feeling sick especially in the morning, I've been sick and at night I've been having cramps, my breasts are sore and tender, ive been going to the toilet quite frequently and I've been eating a lot more then I normally do. I took a test on Monday after however it can up negative, I took another one on Tuesday morning first thing and it still came up negative. Is it took early for me to find out if I'm pregnant

  • By Midwife @Tommys on 7 Jul 2017 - 15:10

    Hi, It is difficult to really advise you as you have not given any dates at all but sometimes it can be too early for a pregnancy test to be able to pick up on hormone changes. If you wait a week and then try a test again, alternatively you could see your GP for a blood test as they are more sensitive than a urine home test. If you think you maybe pregnant then it would be advised to also take a folic acid supplement too. Tommy's midwives.

  • By Midwife @Tommys on 21 Jun 2017 - 16:36

    Hi Jamal
    Yes, it is possible for you to be pregnant. If you had unprotected sex following your menstrual period, then it is possible for you to have conceived in that time. I would be sensible to do a pregnancy test within the next 1-2 weeks. Please take good care of yourself.

  • By Anonymous (not verified) on 16 Jun 2017 - 14:25

    Hi, I've always been irregular but it's always a Friday I have been (on) I can never be certain of the time I will be on as usually I can miss a month then be on again. So it's not really an issue I'd be worried.
    However I have been irregular latelY as usual and can't actually pin point last time I was on.
    Lately Im tired and have hell of mood swings. My temperament is highetend and when I wake I do feel a sense of sickNess, but haven't - apart from today.

    I was pregnant before around 17yrs old. Still irregular and one morning I woke and I just knew, went and got a test and It was positive.

    I can't be sure now because, in a sense I just think I'm Ill constantly, I've been underweight but since this has started. I was 8 stone and now weigh 8.5 stone just within 2 weeks.
    I can hardly eat, I feel dizzy and
    have been known to drop to the floor passing out with high and low temperatures. Cold/hot soaked in sweat. have to weigh my head down to the floor till it eventually passes. I've scared a few people in my presence if it had been in a car I'd have to stop and get the air and just simply fall out in weakness, Or in the bathroom where I can't be moved on the floor. I can't speak nor do I have the power to get up. *(bit never feel sick while the occures)*
    This was before I belive I may or may not be pregnant so you can see why I generally just don't know, If it's my eating or generally feel weak or IllNess.

    Been doctors got blood test - nothing. I know when the faintING spells come on because I have at least 2 minutes feeling of warning, when I know it's gonna happen.
    -- Haven't had one recently apart from withdrawing weakness and sickness feeling and only today I have been sick.

    But if it's not pregnancy for my recent symotons and the GP don't know by my blood results. Then it's something I'd have to wait till it passes.

    I have a boyfriend of 7 years so if I fell pregnant, it would not be a surprise and tbh would be quite happy.

  • By Midwife @Tommys on 12 Jun 2017 - 09:34

  • By Midwife @Tommys on 22 May 2017 - 09:46

    If your last period was 13/5/17 it is not really possible that you are pregnant. A period that is a few days late is not unusual and not something to worry about. Best wishes x

  • By Midwife @Tommys on 24 Apr 2017 - 10:04

    If you think you think you maybe pregnant it would be sensible to carry out a pregnancy test around the time your period is due. Some mild cramping around ovulation can be related to either ovulation or implantation is not uncommon but its hard to determine at this stage which this is. If you continue to feel unwell please contact your GP for advice and support.

  • By Midwife @Tommys on 20 Apr 2017 - 11:59

    Hello. Based on the information you have given here, it is extremely unlikely that you are pregnant. It is more likely that the nausea and fatigue are linked to some other cause. Try to ensure that you are eating well and maintaining a sensible lifestyle. If your symptoms don't improve then I would suggest that you see your doctor. Best wishes

  • By Midwife @Tommys on 19 Apr 2017 - 09:32

    Hi Kimbo.
    Using your first day of your last menstrual period of the 24th Feb 2017, and presuming that you have a regular 28 days cycle, you would currently be 7 weeks pregnant. This would certainly show up on a home pregnancy test.
    If you have not already done so, I would suggest that you make an appointment with your GP who can do another pregnancy test, perhaps a blood test and refer you onto a gynae clinic if you are not pregnant, and have missed a period for unkown reason. Please take good care of yourself.

  • By Midwife @Tommys on 11 May 2017 - 11:25

    Hi, there is a chance that you could be pregnant as you are actively trying for a baby, your period is late and you are showing signs of pregnancy. It would be recommend that you do another pregnancy test in a couple of days, if you still haven't had a period and the test is still negative then please go and see your GP as they can do a blood test to check your pregnancy hormone levels and these are very accurate as the pregnancy hormone is picked up in the blood. Good Luck with everything x

  • By Midwife @Tommys on 15 Mar 2017 - 10:04

    It is possible to become pregnant without having full sex. If you were not using contraception and you haven't had a normal period it would be worth buying a pregnancy test. Then you know one way or the other so you have time to make choices about what is right for you if the test comes back positive.
    Take care

    Hi Midwife,
    I've been troubling with a bit of a yeast infection of late so my midwife prescribed me Fluconazole. I have read that this interferes with the birth control pill Loestrin that I take like clockwork every morning. I have taken 2 doses of this tablet for the last 2 Sundays. I feel a little sick stomach in the mornings and my period is not due until next week. Could it be possible that i'm pregnant?

  • By Midwife @Tommys on 13 Apr 2017 - 14:47

    There is some evidence that fluconazole can interfere with combined oral contraceptives. It is therefore recommended that you use a condom until your next period. The only way to know if you are pregnant is to do a pregnancy test.

    Is it possible to become pregnant after having a tubal ligation? What are the chances of becoming pregnant? I had the tubal procedure over 13 years ago. I am 34 years old and my partner and I do have unprotected sex.

  • By Midwife @Tommys on 13 Mar 2017 - 14:11

    A tubal ligation is a surgical procedure to cut, clip or band the fallopian tubes and prevent an egg from moving from the ovaries to the uterus. It is considered to be 99.5% effective in preventing a pregnancy. Did you have the procedure in this country and are you sure this is what was done? Did you have both tubes tied?

    I have missed my period 6th March and I had a positive pregnancy test. Today I had a little bit of brown discharge after being at the toilet. Am I still pregnant or what can I do? Any advice please? I had a miscarriage 7 years ago and afterwards I had my son. Also 2 years ago I had a miscarriage, too. Both of my miscarriages happened when I was 12 weeks pregnant...

  • By Midwife @Tommys on 10 Mar 2017 - 09:22

    The mostly likely explanation is that the brown discharge is an implantation bleed which commonly occurs around about the time your next period would have been due. However I understand that you are anxious given your history of miscarriage, if you have any further bleeding or pain then go to the GP for a review. In the meantime if you have not already, then I would advise for you to be taking your folic acid and vitamin D supplements. If you would like any further support then please do email us [email protected]

I have also been feeling nauseas and bloated for the past 3 months. Now my period is 5 days late. Is it possible to be pregnant and still having my period?

  • By Midwife @Tommys on 24 Feb 2017 - 10:21

    Hi, it is very unlikely that you are pregnant if you have been having your periods still since having intercourse however I would suggest for you to do a pregnancy test just to be sure. If you have a negative test and these symptoms continue then it maybe worth seeing your GP for a review.

  • By Anonymous (not verified) on 21 Feb 2017 - 20:33

    Is it possible to be pregnant without having any sexual intercourse especially for a virgin girl?
    For example: your partner's penis comes into contact with your body near your vagina.
