Patient: I had my last period on 22th February and had unprotected sex on 4th March. After 36 hours took a plan b pill. After a week had the first period for 7 days. In the meantime after my periods we had unprotected sex after 2 weeks from the 1st period.But I still didn’t get my second period and when I breastfeed my baby (1 and half years old )my breasts are too painful that feels like I cannot nurse him anymore.
