Hi i took the morning after pill after having unprotected sex with my boyfriend. My period came on the 14th of february and lasted for 8days. (Usually lasts 7). I had a 30day cycle before taking the pill. We had sex again on the 2nd, and came around but not in me. Im expecting my period on the 16th (tomorrow). But i havent been experiencing any PMS like i usually will do.(Mood swings, swore breasts) Is this the pill acting up on me? Should i be worried?
