I need help ladies !

So I'm currently on my period. It's my second day on my period. I had sex in the shower with my boyfriend and he came inside me just a tiny tiny but before pulling out. Then I quickly washed it off and we were standing is it possible that I can get pregnant. I figured no because we were standing up so it could've dripped down (the little like 3 drops that got inside me). What do you think ?
