Opill experience ?

an

Hi guys, I’ve been taking the OPill that I bought at cvs as a form of birth control. It’s been two weeks and the only thing Ive had is breast tenderness. I’m just wondering if anyone else on here has tried it & what their experience has been on it. Is it reliable? It’s the first time I ever get on birth control & I’ve been good about taking it at the same time every day, if that makes any difference. Thanks in advance!
