How common are miscarriages?

Miscarriages are much more common than most people realise.

Among women who know they are pregnant, it is estimated that 1 in 7 of these pregnancies will end in miscarriage. Many more miscarriages occur before a woman is even aware she has become pregnant.

Losing three or more pregnancies in a row (recurrent miscarriages) is uncommon and affects around 1 in 100 women.

A miscarriage is the loss of a pregnancy during the first 23 weeks.

The main sign of a miscarriage is vaginal bleeding, which may be followed by cramping and pain in your lower abdomen.

If you have vaginal bleeding, contact your GP. Most GPs can refer you to an early pregnancy unit at your local hospital straight away if necessary.

However, bear in mind that light vaginal bleeding is relatively common during the first trimester of pregnancy (the first 12 weeks) and does not necessarily mean you are having a miscarriage.

What causes a miscarriage?

There are probably many reasons why a miscarriage may happen although the cause is usually not identified. The majority are not caused by anything that the mother has done.

It is thought that most miscarriages are due to abnormal chromosomes in the baby. Chromosomes are genetic "building blocks" that guide the development of a baby. If a baby has too many or not enough chromosomes, it will not develop properly.

If a miscarriage happens during the second trimester of pregnancy (between weeks 14 and 26), it is sometimes the result of an underlying health condition in the mother.

For most women, a miscarriage is a one-off event and they go on to have a successful pregnancy in the future.

Can miscarriages be prevented?

The majority of miscarriages can not be prevented. If a woman has suffered from more than three miscarriages then there are some women who can be helped to keep their pregnancy with medication under the care of a specialist.

However, there are some things you can do to reduce the risk of a miscarriage. Avoid smoking, drinking alcohol and using drugs while pregnant. Being a healthy weight before getting pregnant can also help.

What happens if you think you may be having a miscarriage?

If you have the symptoms of a miscarriage, you will usually be referred to a hospital for tests. In most cases, an ultrasound scan can determine whether the pregnancy is ongoing or you are having a miscarriage.

When a miscarriage is confirmed, you will need to talk to your doctor or nurse about the options for the management of the end of the pregnancy. In the majority of cases the pregnancy tissue will pass out naturally in a week or two. Sometimes medication to assist the passage of the tissue may be recommended  or you can choose to have minor surgery to remove it if you don't want to wait.

After a miscarriage

A miscarriage can be an emotionally and physically draining experience. You may have feelings of guilt, shock and anger.

Advice and support is available at this time from hospital counselling services and charity groups. You may also find it beneficial to have a memorial for your lost baby.

You can try for another baby as soon as your symptoms have passed, although you should ensure you are emotionally and physically ready first.

Having a miscarriage does not necessarily mean you will have another if you get pregnant again. Most people are able to have a healthy pregnancy after a miscarriage, even in cases of recurrent miscarriages.

these stories are so sad i feel for you all, my story started with my first pregnancy in 2006 went without problem and i have a beautiful 8 year old daughter, my second and third pregnancy however was a different story, my second pregnancy lasted 22 weeks in 2009 i suddently went into labour with a girl we named natasha, we were devastated and had her buried, it was the worst time of my life, it took me and my partner a long time to get over it, they said i had a water infection that brought the labour on. my third pregnancy in 2013 was a shock as we didn't want to try again, again i miscarried another girl we named bobbi at 21 weeks. they said the baby and the sack had come through the cervix and i also had a infection. more devastating news, we went to see a consultant after tests etc and she said she didnt know why i had these two miscarraiges and that she believed that they were both seperate issues, i asked for odds in future pregnancies and she said 1 in 3 chance that il miscarry again. me and my partner have decided not to try again, as the pain and the loss of my girls was almost too much, we are grateful everyday for our 8 year old daughter we have with us. stay strong my ladies we are stronger than we give ourselves credit for.

After having bleeding for 3 days while I was 11 weeks pregnant, I was referred to the emergency gynaecology unit for a scan. Today I found out that my baby had no heartbeat and was measuring at only 8 weeks old. After speaking to the nurse about what my options were I went home. I later miscarried my baby in what was around 30 minutes. I am devastated and am so frustrated as I have no idea why this has happened to me. It is such an awful thing to go through and I hope we all find a way to deal with such sad losses :(

In the video Jennie Thomas incorrectly converts one in five pregnancies resulting in a miscarriage to equaling 20% of women who get pregnant. The chance of a miscarriage is 20% per pregnancy. The chance of a women who gets pregnant just twice having a miscarriage is 36% (first pregnancy miscarried = 20%x80%, plus second pregnancy miscarried = 80%x20% and the unfortunate double miscarry 20%x20%). The more pregnancies, the greater the risk of suffering a single miscarriage. It is worrying that NHS puts out such bad science.
