I just want to know what's wrong with me. I went to the doctor's and all he said was they can't find anything wrong with me. All my tests came back normal. For the last 4 weeks i've been feeling nauseous, dizzy, i've had back aches, stomach cramps, bleeding gums. I've gained 14 pounds and haven't had my period in 5 months. It's really starting to freak me out. I thought for sure I was pregnant but they would have detected in the blood and urine test they did. I also took two home tests and they also were negative. Any ideas what it could be...?
