It is possible to get pregnant by having intercourse 53 days postpartum. The timing of the return of ovulation after delivery is most closely related to breastfeeding. Most women resume ovulation between 4 and 6 months after delivery if they are exclusively breastfed. If you don’t breastfeed after delivery, the average time to first ovulation is 45 to 94 days after delivery, and the recovery time for mixed-feeding women is somewhere in between. For women who are not breastfeeding or mixed feeding after delivery, although there is no regular menstruation for 53 days after delivery, there is a possibility of ovulation at this time, so if there is coitus there is a possibility of pregnancy, so mothers should not wait until menstruation recovers to start contraception, but as long as there is sexual intercourse should be contraception to prevent unwanted pregnancies, and if you are still breastfeeding after delivery, you need to be even more careful about contraception. If you are still breastfeeding, you need to pay more attention to contraception. When you have intercourse after giving birth, you should pay attention to contraception, and it is best to choose the condom method of contraception.
