Unprotected sex and pregnancy?

[w0rriedguy90]

My girlfriend had her period on the 18th September and ended on the 22nd September. Today (25th Sep) we had unprotected sex as we were both really drunk and wasn't thinking straight.

I know that most of my ejaculation was not inside her as I pulled out but I'm worried that in my drunken stupor, I wasnt able to pull out in time and some of the ejaculation ended insider her.

Is there a high chance of being pregnant for this? My girlfriend is fairly regular and her cycles are mostly 28 days long with 5-6 days of bleeding.

You are probably in the clear, as she is fertile for many days she truly only ovulates for 24 hours and that is usually about 14 days after her period. So very unlikely.
