I took the morning after pill in august, the period after that was a full 7 days which I read on the box that a longer cycle is possible, up until last month my period has been normal. I am 17, and last month I got my period either april 14th or 15th in school and it came normally for the first few days then after the 3rdmorning it was light, and I had brown discharge and it lasted 7 days. I was either due for my period yesterday or today but I don t have it get, however I have sore breasts, mild cramps every once in awhile, and headaches . Me and my partner do not have unprotected sex but he did rub his junk on my lady part about 2 hours later, I did some research and there could be more reasons why I haven t gotten it yet. Crazy weight gain , alot of stress with school, ect. But its never a bad idea to be to careful Please help!
