I have been with my boyfriend for about a year and a half. But we only started getting intimate with one another. I am his first and he is mine. I have been on my birth control pills "Aubra" for about a month and a half. I am half way done with my second pack. We started having sex after the first pack. We never use a condom and he never finishes inside me. When he does finish, it's always outside of me and into a towel. How safe is this to do? I'm such a paranoid person and I'm scared that I'm pregnant. Last month I got my period and I am due it in about a week and a half.. I am not overweight or on any antibiotics. I take my pill everyday at 10:00 PM sharp.
