Recurrent miscarriage


Sadly, miscarriages are more common than people realise. Around 1 in 8 women will have a pregnancy that will end in a miscarriage. Many more miscarriages may happen before a woman is even aware, she is pregnant.

In some cases it is possible to understand what has caused the miscarriage but in many cases we never know. In many cases the woman goes on to get pregnant again and have a baby. There are however risks that can be removed when trying for a baby

If a woman has three consecutive miscarriages, then we refer to this as a recurrent miscarriage and at this point we will carry out investigations

Recurrent miscarriage

A recurrent miscarriage is where you have 3 or more miscarriages in a row. This is uncommon and affects around 1 in 100 women.
