I am pregnant. And there is some confusion over who the father could actually be. I slept with boy A and did not use a condom-he did not ejaculate to my knowledge. I slept with him again a few hours later and did not start with a condom-he than put a condom on and ejaculated shortly after. roughly 66 hours later i slept with boy B. We started sex without a condom.-it was very brief. He than put on a condom and ejaculated. 15 hours after i started part one of 2 emergency contraceptive pills. I am not sure when I ovulated-and my LMP was determined by an ultrasound. Whos baby am I most likely to be pregnant with? Boy A or Boy B
