My period has always been pretty regular, usually 30-32 days. Last month my period was late by 4 days, but it came normally. I had sex earlier this month one time, and I took the morning after pill, when we first started he penetrated for about 30 seconds and then put on a condom. I took the pill right after. We messed around three days ago, no sex, justouter with hands, I did orgasm. Yesterday I started spotting and it was brown, and today its still there and is dark dark red. O have had occasional cramping. Based on my normal cyle my period should be coming on the 21/22nd (3 days away) but from last months it would be on the 25/26 (7 days away) what could this be?? and should I be worried, since i did take the morning after pill. thanks for any answers.
