How common is miscarriage?

It is natural to worry about miscarriage during pregnancy. Here, we provide some facts about miscarriage in the hope that this will help you manage any anxiety you may have.

Some pregnant women and people may worry about having a miscarriage during the early stages of pregnancy. This may be because they know someone who has been through this experience or because it has happened to them. 

Everybody hopes for a healthy pregnancy and it’s natural to worry about things going wrong. Unfortunately, there is nothing to you can do that will guarantee a successful pregnancy. But there are some things you can do to try and reduce the risk. 

Why do miscarriages happen?

We don’t know why all miscarriages happen, but sometimes there can be underlying reasons for this type of pregnancy loss. But remember that it’s very unlikely that a miscarriage is caused by something you did or didn’t do.

Is miscarriage common?

Early miscarriage

Sadly, early miscarriages are common. In the first 3 months, 1 in 4 women will have a miscarriage.  After 3 months, the risk of having a miscarriage goes down significantly.  

Late miscarriage

A late miscarriage (after 3 months but before 24 weeks) is much less common. This happens in around 1-2% of pregnancies.  After 24 weeks, a baby’s death before or during birth is called a stillbirth. Stillbirth happens in around 1 in every 200 births in England. 

This legal distinction between miscarriage and stillbirth is made on the basis that a baby is thought to have a good chance of surviving if they are born alive at 24 weeks. This can be very upsetting for some parents who have a late miscarriage because they may also give birth to their baby and, understandably, feel that it should be called a stillbirth.

We know this terminology can be difficult for some parents, but you can use whichever language you choose to describe your loss.

Ectopic pregnancy 

An ectopic pregnancy is a pregnancy that develops outside of the womb, usually in the fallopian tube. It affects around 1 in 90 pregnancies. Unfortunately, it is not possible to save an ectopic pregnancy.  

Molar pregnancy

A molar pregnancy is when there's a problem with a fertilised egg, which means a baby and a placenta do not develop the way they should. The general risk of molar pregnancy is around one in 600. This means it is quite rare. 

Unfortunately, a molar pregnancy will not be able to survive. It may end on its own (a miscarriage) or if this does not happen, it's usually treated with a procedure to remove the pregnancy. 

Can you do anything to avoid miscarriage?

Miscarriages very rarely happen because of something you did or didn’t do and sadly there is nothing you can do to guarentee a healthy pregnancy. But there are some things you can do to reduce your risk of having a miscarriage:

Will I miscarry again? 

If you have already had a miscarriage, you may be worried that it will happen again in another pregnancy. Try to remember that most people will only have one miscarriage.

About 1 in 100 women experience recurrent miscarriages (3 or more in a row). But even if you have had several miscarriages, it’s important to know that many people still go on to have a successful pregnancy.

Is it my fault if I have a miscarriage?

It is important to know that miscarriages very rarely happen because of something you did or didn’t do. So if it does happen, it’s very important not to blame yourself.
