Does exercise cause miscarriage?

No. Exercise has not been shown to cause miscarriage. If your pregnancy is uncomplicated, it is safer to exercise than not.

It is natural to worry about miscarriage, especially in the early days of pregnancy and if you have miscarried before. However, there is no evidence to suggest that exercise causes miscarriage.

In fact, if your pregnancy is uncomplicated, it is safer to exercise than not. For example, women who stay active during pregnancy have a lower risk of gestational diabetes and high blood pressure.

“I wanted to wrap myself in cotton wool after my miscarriage and I found it difficult when other mums talked about all the sport they still did - in the first trimester I wanted to protect my baby as best as I could.

If you are concerned about your baby being shaken around as you exercise, don’t worry – this isn’t the case. Your baby is secure inside your womb. However, if it helps with your anxiety levels, go for low impact exercises like walking and gentle swims.
