Girls, the situation is complicated ? We're on breastfeeding, the child is not yet a year old. Today there was an unprotected intercourse, there is a possibility of getting pregnant. And I am not ready yet. The childbirth was not easy. And I don't want to detach from the breast for the baby. Everything happened so fast. Should I take contraceptive pills after unprotected intercourse while breastfeeding?
