Am i pregnant or is something bad happening?

Casey

Im going to lay it all down for you. I dont think its likely at all that im pregnant. On july 3rd (THE ONLY DAY) i had sex with my boyfriend but i had my period start at the end of the month (the end of july). That should signal im not pregnant right? Then today, two weeks ago from when i had my last period, today is supposed to be my ovulation day but im bleeding again? I cant find anything to signal this is another period online so can someone please help me? I really don't see reason why i should be pregnant? Help!
