Suggest Safe Birth Control Options

I am 19. I am on the birth control yaz and I have been for 6 years. I switched over to the generic for the last year but just recently switched back to the normal kind. Ever since I first started having sex I will bleed during sex a week before and a week after my period. Usually I am fine in between. When I was on the generic, I was fine but with our new insurance it s more expensive. I have been checked for STDs and I am clear so I really think the reason is my birth control. I want to stay away from the depo shot and I don t think my body would take to an IUD. What are some other good birth control pills or other options. Or any thoughts on the whole situation.
