What are the chances of being pregnant?

So I wasn’t told before getting my iud removed that I couldn’t have my partner ejaculate inside for a week. I had sex 4days before thinking it wouldn’t be a problem as there was 4 whole days before the gyno would be up there. Now I’m worried about pregnancy..what are the chances if he didn’t fully pull out in time?

It’s not a huge problem if it did happen since that’s the point of getting it removed but I kind of wanted to let my body get back in a normal cycle first.
