The chances of getting pregnant while breastfeeding are very high. As women are in better health and recover more quickly from the nutrients after delivery, ovarian function recovers more quickly, and menstruation can occur after the first month of pregnancy in some mothers. Menstruation indicates that the ovaries have begun to ovulate, and if effective contraceptive measures are not taken during intercourse when ovulation occurs, it is possible to become pregnant. Mothers in the breastfeeding period, due to the influence of lactogen, even if not menstruation does not rule out the situation of ovulation, so do not take contraceptive measures when having sex, just in the ovulation period, the probability of pregnancy is very large. After the puerperium, as long as a woman has intercourse, she must take effective contraceptive measures to avoid unwanted pregnancy. If you are breastfeeding, you should use condoms throughout the entire period to avoid side effects on your body.
