Okay. I had unprotected sex for the first time and my boyfriend slipped out before he "came" and then i had my period a week later. Can i still be pregnant? it's been a month since i had sex. im scared. i've taken 3 pregnancy tests and they all came back negative. idk if it's because i havent been eating right but my stomach has a pudge now and im very self-concious about it. Everyone has told me that i dont need to worry because i had my period after i had sex and that means there is no way i could be pregnant. Could i still be pregnant?
