New Birth Control

I recently got put on a new birth control. I was on my previous for 3 years but seeing as I dont have insurance it was almost 40 dollars a month. So my doctor put me on a different brand and now I'm having all of these crazy symptoms such as nausea,vomiting (every once in awhile), headaches, and dizziness. Has this happened to anyone else after switching? What did you do to help it? When did it stop?
