okay so me and my boyfriend didn't have sex but we were playing around and he cmmed on top of my vagina this happend july 29 2016. I was stressing so much. i begin to have sore nipples and three days after that i took a home preg test they all said negative,but then i started my period and i received my period in August and also September,but i looked in the mirror and saw this line going up my belly button. Im scared. Can i be pregnant. Im only 17 and i want a future not a baby.
