I just started taking birth control and have not been on it for a month yet. My boyfriend realized the condom broke, so I took plan b the next morning. I still am taking birth control and was wondering when I can have sex relying on the pill only, since my gynecologist said the first month I need to use a condom but after that I am fine. So can I have sex now without a condom even if I took plan b? I was wondering if it affected my month and would need to still using condoms while on birth control.
