Me and my bf had unportected sex 2 weeks prior to my period starting. i took the morning after pill first thing the next day within 24 hrs of unprotected sex. my period is already 5 days late. my periods are regular. can taking the morning after pill delay my period? i have been having cramps lately that come n go throughout the day for the past 5 days and have been feeling pretty tired lately. could i be pregnant or is the morning pill causing a delay? any advice would be helpful.
