My girlfriend and I had sex about a week back. She was only about 17 days on the pill. I still wore a condom but it broke. Before that I was going to cum so I pulled out but nothing happened. I must've just missed it. The last time I had ejaculated was at least two days ago, so I highly doubt there was any sperm. But if I nearly ejaculated, could there be sperm? Could she be pregnant?
