i’m 16, and i just got back on my bc pills after a while due to my terrible reaction to the last ones i was on. I just took my 7th one tonight, but i had sex before i took my 7th pill. we didn’t use a condom, but i made him pull out every couple minutes to make sure he didn’t cum inside me. the last thing i need is to get pregnant! i’m sure i’m not going to get pregnant, the box says 7 days and i took my 7th one so i’m sure i’m good, but i also am prone to worrying about EVERYTHING!
