Continue or not?.

So I started BC on the 8th since my period came out more than it seemed it was going to be. The first week was okay only side effect I had was that I felt bloated every night and tenderness on my boobs. But this past week the, idk if it’s the BC or antidepressant pills I recently started taking, are making me feel really nauseous and haven’t really been feeling good at all. I want to stop taking the BC cause I’m honestly hating this nauseous (can’t really keep anything down) feeling but idk if I should since I’m really trying to regulate my period. What advice would you give me??.
