Side effects of birth control?

Hi ladies question. So I am on birth control pills. I have been taking them everyday at the same time. Well when I got off my period 1 day later I started to feel nauseous. It has been like this everyday now since just extreme nauseous like I’m throw up. It hit in the morning afternoon. Could this be a side effect from the birth control pills? I have been on them for 3 months? View insights

It could be the pill. They can mess with hormones.
