Last night, boyfriend and I had a condom break. He pulled out immediately and didn't ejaculate. I feel like we should be okay, but condoms are our only form of birth control and I'm approaching the most fertile part of my cycle (yesterday was the 12th day of my cycle, and though I'm not noticing any mid-cycle ovulation discharge, I should be seeing that any day - usually ovulate on or about day 14-15). Should I take Plan B or is it probably unnecessary since he didn't ejaculate? There shouldn't have been sperm in any pre-cum since he had just gone to the bathroom.
