I'm 18 and I'm unsure if I'm pregnant or not. I haven't had my menustrual cycle in 2 months. A week after I missed my cycle I went to the doctor and they said I was not pregnant but the doctor said it takes a while to know. So the doctor said come back in 2-3 weeks, but a week after that I brought a pregnancy test from the store and it said I was not pregnant. I've been sleeping a lot and I've been having cramps also, I don't know what to do…. My boyfriend believes I'm pregnant because he's eating alot more and he's always sleeping like me. If I am pregnant I'm keeping my child.. What do you all think about my situation?, Do you all think I'm pregnant or something else is wrong?????
