Chance of me getting pregnant even tho he pulled out

*DISCLAIMER: I WENT TO A CATHOLIC SCHOOL WHERE SEX ED WAS NOT TAUGHT SO I FEEL REALLY DUMB ASKING THIS ALREADY PLEASE BE NICE :-(*

I had sex with a guy Saturday night and we started with a condom and finished without one. I have the IUD so either way I’m still relatively protected from pregnancy. He did not cum in me, but is there still a chance I could get pregnant without him cumming in me???

Sorry if this is worded weird and doesn’t make sense
