I havent had a period in 3 months but everytime i take a test its negative. I was on birth control but i wasnt taking it great(4-3 months ago). Now im hoping i am pregnant and everyone asks me if i am and when i talk to my friend about my symptoms she says she thinks i am. Im bloated, tired, gasy, cant stand chinese food anymore, my stomach is hard/hot, I have a craving for cheese(wierd), i frequently urinate, and i dont go number two as often as before. what are your thoughts?
