I have taken two pregnancy tests, both showed up negative. But i didn't get my peroid for the whole month of may, and i never miss my periods, i'm a regular girl when it comes to that. And i can't keep my food down, i throw it up. and, i still pee like crazy and i keep craving chocolate and pizza. My boyfriend and I had sex.. we.. used the pull out method.. and okay i know it wasn't responsible.. but yeah now i just need to know if i am or not.. and i don't know what to do about it. Should i see a doctor, should i take another test, could i even be pregnant???
