My girlfriend and I ALWAYS use spermicidal condoms during sex, but a few weeks ago after her period, I penetrated once meaning i put my penis in and than pulled it out, that was it, I did not ejaculate it was just to see how it felt. Well since then, we've had a condom break and i immediately pulled out and than shortly thereafter ejaculated onto my bed. She hasn't had her period yet (she's got a week to go), but she asked when her last period was and it scared the hell out of me.

Now I know that sperm takes 3 days to mature, and I try to masturbate every other day so if something DOES happen, the sperm aren't mature.

Since I use spermicidal condoms correctly, and masturbate often, is it likely that she's pregnant or are we just freaking out over nothing? We don't' use birth control.

I suggested a test, but she freaked out because she's scared ****less of the realization.
