Silly question but I’m still so anxious

My bf and I were fooling around, I was giving him a hand job and he was fingering me. He touched the head of his penis and got some precum on his fingers and then went back to rubbing my clit and a couple minutes later he fingered me again.

I’ve heard so many mixed answers on whether or not this could get me pregnant. I’m getting an iud this week and I’m just so scared that by some crazy fluke I’m going to end up pregnant. Is it likely??
