Most people who are breastfeeding have irregular periods due to higher lactogen levels. Most of them are postponed, but there are individuals whose periods are more regular and are on time. Most patients whose periods come on time do not lactate very well. Therefore, there is individual variability in whether or not your period can come normally during breastfeeding, and there is no uniform standard. If your period is irregular during breastfeeding, then contraception must be done properly. Because irregular periods make ovulation irregular, contraception is more difficult. As long as you do not intend to have children with intercourse, you must do the whole contraception at all times, so that you can avoid unnecessary trouble. This is because having an abortion while breastfeeding is extremely harmful to the mother and child.
