here the past month I've gained weight, all while eating right and exercising. I've also, began to throw up randomly. mostly after eating because a lot of stuff no longer agrees with my stomach. tonight I had a bratwurst and immediatly I regurgitated it. most of the weight gain is in my abdomen and legs and face. I pee wayyyy more often then I used to and have I am always hungry. certain smells and tastes or textures make me I'll and I'm constantly having a headache and backache. my fiance thinks I'm pregnant considering he already has a child. I do not have any children. any thoughts? (no I have not taken a test yet)
