End of last month I stopped taking my birth control gianvi because it failed on me. So I took it the beginning of this month and last Saturday my bf and I had unprotected sex. He ejaculated inside of me but I missed 2 gianvi pills Saturday and Sunday. I did take 1 pill Monday but got really sick and started having diarrhea. Then Tuesday I took another one and started feeling neasous. Could I become pregnant? I decided to stop taking the pill just in case. Should I continue he taking the pill?
