Menstruation will typically return to normal one month after a miscarriage. In some women, ovarian function may recover slightly later, but no later than 45 days. If a woman has not had her period within 45 days after a miscarriage and has engaged in regular sexual intercourse during this time, it is essential first to rule out the possibility of another pregnancy. If pregnancy is excluded and menstruation still does not occur, it may be due to incomplete recovery of ovarian function. In such cases, an ultrasound examination can be performed first to assess the thickness of the endometrium.
