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
- 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.
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.
Tommy's carries out vital research into miscarriage – find out more about our miscarriage research.
A chemical pregnancy is the term given to a pregnancy which ends in miscarriage before the fifth week of gestation.
This type of miscarriage can be really shocking for a mother.
If you start to miscarrying naturally, and experience some bleeding, this indicates that the pregnancy is over and the process of losing your baby is underway.

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

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

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?
