After a miscarriage, the uterus’s inner layer (endometrium) is damaged and needs some time to expel all the residual endometrium and for the new endometrium to regenerate. Having sex while the endometrial layer is still regenerating increases the risk for infection. A woman's recovery time after a miscarriage depends upon the age of the previous pregnancy. You can typically resume sexual intercourse as soon as vaginal discharge or bleeding stops (about 2 weeks after a miscarriage).
