In the past, gynaecologists advised women to wait at least three months before trying to become pregnant after a miscarriage. However research has shown that the chance of a healthy pregnancy is no different if you try again after the first normal period after the miscarriage. There is no benefit from waiting and many women want to try again as soon as is safe. However make sure that you feel ready psychologically. It is healthy and normal to grieve for the lost pregnancy and not everyone wants to be pregnant again immediately.
