Help?

Okay guys. I never post in here but I need some advice.

I recently had sex with a friend of a friend type thing. Anywaysss, it was just your typical one night stand. We started having sex before any foreplay or oral and then when we went to change position I felt something wet drip down my leg. So I freaked out and ran to the bathroom. When I got there it looked like he came in me. Like so much thick white creamy type stuff. We only had sex for like two minutes and he swears he didn’t finish but I don’t really know him so I don’t know. I never have any issue getting wet but I have never been THAT wet. And I doubt that’s it because I wasn’t even that turned on by him...

I’m kind of freaking out. I’m supposed to start my period this week. Any ideas what that could have been?
