i am sexually active. and i don't use condoms and im not on birth control.and im only sleeping with one guy, who is my boyfriend. but for the past two days ive been light headed, tired, i feel yucky and like im going to vomit but i don't. and im peeing like crazy ive peed 8 times since 9 o clock this morning. There seems to be a lot of pressure on my bladder. it feels like i have to pee all the time. It doesn't burn either. I took a pregnancy test two weeks ago and it was negative. is there any way it could of been too early for a pregnancy test? what do you think could be wrong wit me? my last period was on october 13th and it was wierd. then i got it again two weeks later but it didnt seem like my period it only lasted an hour or so and was very light. help me could i be pregnant
