I ve been having problems with my stomach for several years, i can feel something moving inside, causes bad pains, if I m having sex it feels like my stomach has a tight knot and hurts bad and sometimes cause me to bleed after sex, i constantly have sharp pains on the lower left side of my stomach and my stomach has now started swelling like I m pregnant but I m in so much pain. Can someone please tell me what s causing this? I m tired of hearing its normal when i know it s not!
