hi, im 15 years old and i lost my virginaty about 5 or 6 months ago i didn't use a condom and i wasent on any type of birth control but every pregnancy test has come up negative. I have had my periode but it only lasts 1 day and its very light not normal. a few days ago i got a sharpe pain in my lower stomach almost like someone kicking me but from the inside. I have had nousia but not pucking and head aches and dizzyness,
WHAT COULD THISMEAN?
