It is possible to have a pregnancy while breastfeeding because a pregnant mother will have a normal period 1-2 months after a normal delivery if she is not breastfeeding. The date of menstruation is not always the same when the mother has to breastfeed her child normally. Sometimes there is no menstruation during the whole breastfeeding period, or there is normal menstruation after 1 month after the birth of the child, and there are cases when menstruation occurs after 6 months after the birth of the child. However, if you do not have a period, you are still ovulating. Therefore, if you have intercourse during breastfeeding and do not use contraception, you may conceive even if you do not have a period, so you need to pay attention to contraception.
