So last night my boyfriend and I had sex without a condom and he ejaculated inside of me. The thing is, I'm scheduled to take Nuvaring out tonight. I'm hesitant, though, because I read somewhere that sperm can linger in the vagina for a few days. If I take Nuvaring out tonight, is there any chance that I'll get pregnant? I don't really want to take it out I a week but if I must, I will.
