My boyfriend and I use condoms during sex. I am not currently on any other form of birth control, though I have a doctors appointment coming up to talk about getting birth control. During sex today, the condom came off inside me after my boyfriend came. Like, his penis came out, but the condom didn’t. I don’t think any got inside me and if it did, it was a very small amount. Also, my period is starting in the day or two. My question is should I get Plan B in the morning? I am short of cash, and while I’m pretty sure there’s nothing to worry about, I can’t help but worry. Any thoughts?
