Is my dumbass gonna get pregnant??

So I just got my IUD out after 8 years (the non hormonal) a couple days ago and just started taking my new BC yesterday... well last night my bf and I are having sex for a full 10 min before I realize oh fuck we need to be wearing a condom ( I’ve been on birth control for 11 years so it totally slipped my mind that I was unprotected in the moment) so we stopped and switched to a condom. So I wouldn’t normally be worried but I look at my app today and my most fertile day is tomorrow 😅😅😅 am I gonna get pregnant? It wouldn’t be the end of the world since we have talked about it and both want kids but what are the chances that the day after I get my IUD out I get pregnant from some pre cum
