I had sex with the guy I'm seeing last Thursday night (week ago), it was unplanned and unprotected, which we never do, but he pulled out and didn't come in me. For whatever reason I didn't think I needed Plan B, which is odd considering out of all the times I've taken it this was the time I probably should have most. He insists he's positive we're fine, but I ended up freaking out when I realized I was most likely ovulating at the time and took it approx 80-82 hours after we had sex, so just over the 72 hour mark. The twist is I had taken Plan B about 3 weeks before because we thought the condom may have broken, and that time made my period come 2 weeks early, 11 days after my last one, ending a few days before we had sex last week. Going by that last early period, my next one should start around the 19th, but I've been beside myself paranoid that I could be pregnant.
