During the postpartum breastfeeding period, most of the menstruation can come only after 6 months, and the menstruation is irregular during the breastfeeding period, sometimes the volume of menstruation is low, sometimes the duration of menstruation is longer or the interval is longer, which is a common phenomenon, because the secretion of lactogen during the breastfeeding period will affect the normal ovulation. However, some people are not able to have their periods until about 1 year after delivery, which is also a normal phenomenon and not a cause for concern. Ovulation will occur before menstruation, so some people can get pregnant without menstruation during breastfeeding. If you do not have the requirement to have children, you must take effective contraceptive measures during breastfeeding to avoid unwanted pregnancy, which will have a significant impact on your body.
