There are chances of pregnancy during breastfeeding. After delivery, the maternal menstrual cycle undergoes a new adjustment due to hormonal fluctuations. Mothers who are not breastfeeding usually menstruate 6 to 8 weeks after delivery and ovulation resumes at 10 weeks. Breastfeeding mothers usually menstruate 4 to 5 months after delivery, and some mothers do not menstruate for the entire breastfeeding period. For those who return to menstruation later after delivery, ovulation usually occurs before the first menstrual period. Since there is ovulation, if the mother’s fallopian tubes are open, her uterus is well recuperated and she has intercourse, there is a chance of pregnancy. If you do get pregnant while breastfeeding, you should go to the hospital as soon as possible. If the uterus is not recovering well, it is not good for the mother or the fetus to get pregnant, so you should consult a medical professional for help. It is recommended to take proper contraceptive measures during breastfeeding.
