So I'm 14 years old and i had sex with a guy who is now my ex and recently i've been having back pain, rib pain, sickness, my stomach hurts and looks bigger, i'm tired a lot, i eat a lot more often, i use the rest-room a lot more often. I just got off my period so i'm a little confused. All things things were happening before i started my period so i thought it had to do with it and that it would go away after my period stopped but it didnt so i'm afraid i might be pregnant but I havent been pregnant before so I have no idea.
