Hi I am 13 years old. My stomach has been feeling really weird lately. Here is what I have/feel ... gas, conctipation, nausea, sore breast, cramps on the stomach but no period, heartburns, stomach burns, blurry vision/ feeling dizzy every time I get up, depressed a lot, my stomach looks bigger at the bottom and decreased appetite.. what does all this mean ? I have I line that goes to my belly button and down, I've heard only pregnant people have this .. is that true? It seems as if I'm pregnant but I never really been sexually active and never had a boyfriend. I've only masterbated ( a lot of times) there was some times when I masterbated naked and with clothing on. But that's it. I have all the symptoms of pregnancy so I do think that I can be because of the symptoms but I don't recall being near a boy who could have gotten sperm in my vagina. I do have some symptoms of stomach cancer though... ( listed above) my stomach feels hard and heavy and full ALL the time.
