I've been feeling full for days now help?

For the past few days I've noticed my stomach feeling full all the time. I don't feel hungry but sometimes I just eat because I have to. I'm planning on not eating at all today and just drink water and the reason is every time I eat something even if it's small I get even fuller and uncomfortable. It almost feels like there's air in my stomach. I do have a bowel movement but I still feel full so it's not constipation. I don't have health insurance until maybe two months from now since I got a job starting July 2nd. So any advice? before going to the doctors?
