Ok, I'm 19 & for the last couple weeks every time I try to eat I start feeling nauseous after a few bites and can't continue to eat. I have no clue what's going on. This happens every single time I try to eat no matter what it is. It feels like my stomach just doesn't agree with anything, also sometimes my stomach trembles inside I've never felt that before, I am sexual active I come on my period in a few days so that will rule out pregnancy, I'm just not sure what the problem could be , I don't have much more detail but any advice would really be appreciated
