HELP! Last month I was having mulitple pregnancy symptoms like; stomach cramps, back aches, heart burn/indigestion, heat flashes, sick to my stomach(never threw up), constantly tired, and out of breath. I took one test, a little to early, it came out negative. Two weeks later I started but I was 2-3 days earlier than usaul. I took another test a week after I stopped and it came up negative. I have been in basketball lately and whenever we have to jump rope or jump at all, my lower stomach hurts and feels like there is something atttached to me, inside, and when I jump there are sharp pains, feeling like something is weighing my stomach down or pulling on it everytime I jump. I told my b/f about it and he said I just need to stop worrying. But the other night when we did things he said he could feel something inside of me, later that night i had really bad heart burn to the point where I could barely breathe and if I did it was small and fast. I am a little worried on what this could be. I was wondering if there is any possibility i could be pregnant, or if it could be a tumor of some sort, cancerous related or not. In any way should I be worried about all of this?
