I had sex at the end of july . Days passed and I Had been very dizzy and felt very sick. my period never came on August 12. Five days later I had blood clots and blood and it stayed on like a normal period. (3 -4 days). Me and my boyfriend had sex and it was kind of burning but not tooo much and I start bleeding with a little blood clot. But the weekend of my period I felt something real wet in my booty and I wiped it and it was a little blood. I thought it was my period ready to come on but it wasn't.
