hello. im really having a hard time right now. for the past 4 weeks ive havent been feeling well. ive had mild to severe nausea 24:7, headaches (i never get headaches), increase in appetite all the while feeling queasy, mood swings, back pain, cramps, my hips hurts, weird "flutter" feeling, my boobs are tiny bit sore, but dont hurt unless pushed on, and my feet feel strange. i thought i might be pregnant but i have taken 3 urine tests and they were negative. i dont have insurance and i NEED to know if im pregnant or what else it could be. help?
