It can take up to 6 weeks for your periods to return after a miscarriage. This is because your body is still swimming in hormones associated with the pregnancy.
In general, the medical community tend to recommend that you wait at least 3 months following your miscarriage to try again. This 'rest' period is to give you time to process what has happened: emotions and bodily changes. Fortunately, miscarriage is usually a one-off occurrence, and most women will have a successful healthy pregnancy following a miscarriage. However, if you have had multiple miscarriages, check with your doctor if there is a need to conduct tests to check if there is an underlying cause of your miscarriages that may require treatment before attempting another pregnancy.
If your miscarriage is associated with a molar pregnancy (a pregnancy in which the placenta becomes a noncancerous tumour that grows in the uterus), you may need to wait 6 months before trying again.
