Hey guys! I have some questions I would like to get answered. 

I took a pregnancy test yesterday and it came back negative, i put it in my coat pocket and 1 hour later i looked at it again & it was positive. i became really worried, i am only 16! The next morning i woke up and i had started my period & just to remind you i am on birth control. i took another test this morning & it was negative. so what do you guys think?
