No period in almost 3 months. I drink at least 8 to 9 bottles of water a day because I'm always thirsty. Sometimes I even wake up in the middle of the night thirsty and have to drink 3 bottles before I go back to sleep. I'm always tired and I feel bloated. Whenever I eat I get very nauseated, but never vomit. My stomach sometimes jumps and I have 3 red stretch marks(to be exact) on my lower stomach.Can someone please tell me what's going on?
