The pill

I’m in a predicament I don’t know what to do. I currently took the pill when I was 13 because I was young and dumb but I came off it when I turned 16.. I started taking it again because I was in a serious relationship and kind of wanted to be safe as well as using condoms. But the only down fall is when I recently started taking it I was being sick all the time, I wasn’t eating 3 meals a day it was a struggle to even eat one.. what do I do xxx
