We still don’t know why all miscarriages occur. That’s why Tommy’s has opened the UK’s only research centre dedicated to understanding miscarriage and preventing it.
1 in 4 women suffer a miscarriage at some time in their lives, and a small proportion of couples suffer multiple losses. Only 1 in 100 women suffer three miscarriages in a row (recurrent miscarriage) and most couples who experience a loss go on to have a successful pregnancy in the future.
It’s important to know that the vast majority of miscarriages aren’t caused by anything that you or your partner have, or haven’t done.
If a miscarriage occurs during the first trimester (the first 12 weeks of pregnancy), it’s usually caused by problems with the unborn baby. About 85% of miscarriages occur during this period, and are known as “early” miscarriages.
During the second trimester (between weeks 13 and 24, a “late” miscarriage may happen as a result of an underlying health condition.
Factors that increase the risk of miscarriage
- Getting older. A woman of 30 has a 20 per cent chance of miscarriage, but a a woman of 42 has a 50 per cent chance of losing the baby. This is because, as you age, the quality of your eggs diminishes.
- Underlying health problems, such as poorly controlled diabetes.
- Lifestyle factors such as too much caffeine , heavy drinking, smoking and using recreational drugs.
Lifestyle changes you can make
There is clear evidence that your lifestyle can affect your chance of having a baby, so there are several things you can do to limit the risk of miscarriage and increase the chances of a healthy pregnancy.
You should consider:
- Stopping smoking
- Losing weight (if you are very overweight or obese)
- Eating a healthy diet
- Taking regular exercise
- Taking folic acid (or a multivitamin specifically for pregnancy) whilst you are trying for a baby and during the first 12 weeks of pregnancy at least
- Limiting your alcohol and caffeine intake (no alcohol at all is best, and caffeine at a minimum)
- Not using recreational drugs
All of these things we know will increase your chances of a healthy pregnancy.
Common misconceptions about miscarriage
Many women and couples who have had, or are experiencing a miscarriage, worry that they may somehow have caused it to happen. There are many common concerns which simply aren’t linked to miscarriage at all.
- Your emotional state, such as stress or depression
- Having a shock or fright
- Exercise (but do consult your GP or midwife about how much exercise is suitable)
- Lifting or straining
- Working, even if it involves sitting or standing for long periods
- Having sex
- Travelling by air
- Eating spicy food
None of these factors have any known link to miscarriage.
How Tommy's research is finding out why miscarriage happens
Tommy's carries out vital research into miscarriage to understand it better and find out why it happens. This animation below explores the 'checkpoint' theory, which shows that the pregnancy has to pass three stages in early pregnancy where miscarriage is more likely.
A chemical pregnancy is the term given to a pregnancy which ends in miscarriage before the fifth week of gestation.
Missed miscarriage can come as a big shock as there are none of the usual signs of miscarriage, such as bleeding or pain.
If you start to miscarry naturally, and experience some bleeding, this indicates that the pregnancy is over and the process of losing your baby is underway.

I don’t know where to begin with. This feeling inside me is indescribable. Day before yesterday i went for my regular scan and found out that my baby has no heartbeat and stopped growing since last two weeks. But i had 3 normal deliveries before this, no complications. How can it happen all of a sudden. All my blood and glucose test were normal.i am waiting to naturally deliver my missed miscarriage since 2 days no cramps ,pain or period .All I believe is i will see my little angle in the heaven .i hope and pray no parents should go through such difficult situation where Your happiness turns into grieve and sorrow. That one sentence of the sonographer felt like a knife in my heart, and what is more frustrating is doctors have no answer to what could have cause this to happen.

I would like some advice, Iv had 2 misscaridges now, 1 at 6 weeks and other 1 at 11 weeks 2 days. I have rhesus negative A blood and no one has told me about the anti D injection. Could this be why I had a miscarriage?

I'm 3 weeks pregnant is there still a chance I can have a miscarriage this early? Because I've been having trouble eating, breathing, I'm always nauseated while smelling certain things and show mood swings... I need to know what should I do. This would be my first, even though I wouldn't mind having a child, but it's just not the time or place for me to have one until I'm financially stable to have a baby.

Sorry to hear from all of u
I had recurrent 3 miscarriages
First 2 were natural conception third one was IVF ...that too failed
All my babies heartbeat stops suddenly after 6 weeks
Doctors are not able to give a sound proof reason
But I still remember that my first gynaecologist after my miscarriage had suggested me tuberculosis drugs for eliminating all the viruses or bacteria which are present in females genitals which is usually left unrecognised by us ...
Feeling regretted should have started at that time only
God please listen to our prayers and bless everyone who are waiting for their child to be born
Please listen to our prayers

I had consecutive miscarriages thrice. The first one was at 7 weeks, no heartbeat. Second one was at 8 weeks 4 days, we lost both the heartbeats. Third one was at 8 weeks 3 days, we lost both the heartbeats which happened today.Trying to get pregnant with IVF itself was a very emotional, having miscarriages is emotionally draining.My doc couldn't identify the problem why it was happening around the same time. Looking for answers. Is anyone having the same situation or anything to share plmk.

This was my first pregnancy, I was experiencing lots of pregnancy symptoms like breast pain, heavyness, nousea, craving for food, cramps at Tommy for whole month. After 1 month of waiting I did the home pregnancy test which shows it was positive. I was very happy, to confirm it I took the blood test to check my HCG level in blood, it shows I was 5 week pregnant. I waited for 2 weeks to start my antenatal care. After 2 weeks in the ultrasound, it shows there is nothing in my womb. By gyno advice I took the blood test to check my HCG level, it was very low. Then only I came to know that I had a miscarriage. I m shettered by pain and emotional shock. I m still unable to understand what happened.

I have lost 5 pregnancies. On February 2019 I had a ruptured deadly etopic pregnancy which resulted in having my right Fallopian tube removed. It took me 2 years to get pregnant but before that i had 3 miscarriages no more than 8 weeks. Just this may I found out I was having twins. Yet I have PCOS. only have 6 periods in 2 years. Well I lost them after going to the ER because I had a dream that I lost my babies and I did. I carried my babies in my tummy for 1 month before I passed them. They told me I have low progesterone and will need medication or injections throughout my whole pregnancy when I decide to try again.

I have just had my second miscarriage in 6 months. This one was natural at 11 weeks, my previous was a missed miscarriage at 13weeks, surgical management and was due to Edwards syndrome.
I am34 with 3 children all normal births, 2 girls and a boy. I just don't understand why this is happening. I keep being told "just bad luck". It feels like it's something more.
Is there anything I can do to check the quality of my eggs? I just don't understand why this is happening after 3 healthy pregnancy's.
Both losses were following a scan hearing heartbeats and seeing a normal fetus, it seems like when the placenta takes over the loss occurs and i just don't know what i can do to prevent this from happening again?

Hello, I hope your okay, I’m the same as you I have had three healthy babies 2 girls and one boy, I have also had three miscarriages but and currently only a couple weeks pregnant, I am fretting incredibly so as I’m unsure on whether this baby will survive or it may be my fourth miscarriage in a row. The one thing I do know is that after 2 miscarriages the chances of it reoccurring is 28% and after the third it’s 48%. It’s a devastating problem for any woman to go through! I really do understand your pain and concerns, I lost one at 13 weeks, one at 8 weeks and one at 6 weeks, all after hearing heartbeat, my last miscarriage was happening whilst I had my scan and they told me my baby was fine when in fact it wasn’t because the next day I went back to hospital and I was having my baby taken away from me! I really want answers too! I wish they could scan me to find out what’s wrong but they won’t

Miscarriage.I had two miscarriages both at 5weeks ...what could be the reason because the doc could not identify the cause of loss
By Sarah (not verified) on 4 Jun 2019 - 09:41
First was in February at 12 week scan showing 5- 6 week embryo. I grieved and put it down to one of those horrible things. We tried again after my first full cycle and I couldn't believe my luck to fall pregnant so soon. I had a 7 week scan and everything was great with a heartbeat. So I was sure it would be all okay. Only to find yesterday at my 12week scan a lifeless baby at 11.4 weeks. I already knew I asked them to turn the screen off before starting. Both times I had zero bleeding. Are there any online chats I can use to talk to others. Once I could cope with but 2 in such quick succession is proving very difficult. I'm not myself at all

First was ectopic preganancy, second I had miscarriage at week9 as baby's heart beat was not developed. Doctors are unable to tell the reason of miscarriage. Please help
By Anonymous (not verified) on 10 Jul 2018 - 19:11
I've had 2 ectopics and had my left tube removed since then I've had a miscarriage at 13 weeks and now another at 6 weeks. Nothing present during the early scan and HCG level is 166 so nurse said it's an early miscarriage. I've had a blood test to check for Thrombophillia, but awaiting the results. Keep being told that NHS won't do anything until I've had 3 miscarriages, I am going to go private as I can't take the pain and loss anymore but is there something specific I should be checking for as to why I keep having these loses such as clots or cervical checks?
By Midwife @Tommys on 12 Jul 2018 - 14:08
I am so sorry to hear what you have been through and continue to go through. The general guidance is that the NHS do not normally offer tests and investigations until three consecutive miscarriages, which is what you have been told, and it is understandably extremely frustrating and upsetting. Sometimes some basic test are offered but this is down to the discretion of the health professional and they are not under any obligation to do so.
With regards to cervical checks, it would be unlikely that it was your cervix that is the problem as all your losses have been in the first trimester, cervix problems are often a cause of second trimester losses not first. You are already having a blood test for thrombophillia, so when you get the results of this this may give you some more information about if you need to take aspirin and/or heparin in next pregnancy.
It is completely your choice if you would like to access private care in the meantime, if this is an option for you. They will discuss what tests they can offer you and what their plan would be based on your history so far.
I wish you all the best, please do be in touch with us if we can support you further.

I had a miscarriage at 11 weeks. I had a scan at 10 weeks strong heart beat and perfect little fetus developing. I got a temperature and couldn’t reduce it by the 4 day I had pain and cramping told not to worry by early pregnancy unit and then at 13 week booking had a scan to check and all had gone. I believe the temperature a virus cause the miscarriage but when I speak about this now people think I’m wrong. That it must be genetic. Why do health professionals not listen to patients after miscarriage - maybe if we did we would understand much more about the causes and risks.
By Midwife @Tommys on 10 May 2018 - 14:36
I am so sorry that you lost your baby and you feel as if nobody has listened to you. Unfortunately, there can be many reasons for miscarriage, so it really is difficult to know if your virus/temperature may or may not have contributed in some way to the loss. It is possible that it wouldn't have helped, but i feel that it is foolish of your team caring for you to dismiss it entirely. However, whatever the reason for it, it is not possible to determine it for sure. It sounds as if you are really struggling emotionally with the loss, which is totally understandable. If you feel you need some advice and information about how to access counselling, we can assist you with this. You can get in touch via email [email protected] or 0800 0147800
I really hope that you are doing ok and get in touch if you need us
All the best

The exact same thing happened to me at the beginning of this year. I’m still convinced it was my flu and high temperature over 3 days or so that caused it after my healthy scan at 10 weeks

I saw,the baby and HB at 8.5 weeks and all looked OK. At 12 weeks there was no HB and baby measured 8.2, days. The midwife said the baby likely passed after the internal scan. Could the scan be the reason I miscarried. When she was checking stuff it did hurt me
By Midwife @Tommys on 7 Aug 2017 - 11:51
I am so sorry about your miscarriage and hope that you have good support to help you. There is no evidence to suggest that a vaginal scan can harm the growing baby. It is more likely that the timing was by chance. Best wishes to you x

By [email protected]'s on 19 Jul 2016 - 10:07
We are very sorry for your and your daughter’s loss. Internal examinations are not normally carried out in early pregnancy unless there is a specific reason for it. Whatever the reason was, an internal examination does not cause miscarriage or pregnancy loss. Without knowing more about your daughter’s pregnancy history we can’t give any more information. If you (or she) would like to call us on 0800 0147 800 or email on [email protected] we can talk it through with you. Sorry again for your loss.

My daughter was 9 weeks pregnant and miscarried, this one day after an internal examination which expectant mothers I am told have to go through. Could this internal examination have been the direct cause of her miscarrying her baby?
