I had unprotected sex with my boyfriend Jan 4th, 7th, & 9th. He didn't ejaculate inside of me, but after he pulled out, 15 mins later we had sex again. So the next day I go on my app for my period to mark dwn the days tht I had sex & I was ovulating the 4th. My period was supposed to come the 23 but I ended up getting it the 18th. It was a weird period it was light then it would stop for two whole days then it was enough for a tampon. Then on the 4th day it was brown. Then on the 23 nd 24 nd cramping it was brown. My period only last 4 days normally. So I think nothing wrong then Im at work on Saturday and im extremely dizzy and tired. So I was just wondering what was going on?
