My girlfriend and I had unprotected sex. Before I came, I told her to get off and I pulled out. I stroked it before any sperm or semen came out. She got her period 2 days after. Her period lasted 8 days.

Well, next time make sure its protected. And if she got her period two days after...MAYBE. Most likely not though. It can take up to 72 hours for 1 sperm to reach an egg though. So I guess...wait and see. And be more protective.
probably not. next time if u don't use a condom or something, use the morning after pill
