Birth control

I just started taking Junel Fe two days ago and after I take it I get terrible stomach pains. I've been overly emotional from it and I have anxiety that's been worsened due to my fear of any side affects. My period ended like the day before I started taking it and I'm pretty sure I'm breaking out from it. I really don't want to take it anymore but I have cysts on my ovaries and was told it would help prevent new ones and that I basically "need to be on it" since I have sex. I don't know what to do because I don't know anything about birth control and I don't want anymore cysts but I seriously hate this birth control and have never wanted to take it in the first place. Has anyone been through this and have any advice if so?
