Usually, there will be ovulation within 1 month after spontaneous abortion, the specific time may be about 22 days after the abortion, and the ovulation period is about the same as the normal time. In addition, if the uterus is purged after spontaneous abortion, it may cause some damage to the uterine lining, ovulation may be a little later in this period, and the menstruation may be abnormal and irregular, but usually 2-3 months after delivery, after the uterine lining recovers, and menstruation is resumed, the function of ovulation will be resumed. After spontaneous abortion, it is recommended to use contraception for 3 months before considering having a baby, because the uterus needs some repair and recovery time, so do not get pregnant too early after spontaneous abortion, otherwise it will also cause some harm to the woman.
