What are the chances of me getting pregnant?? condom + pulling out during fertile window/ ovulation. SHOULD I TAKE PLAN B????

So me and my SO had sex during my fertile window/ while i was ovulating. We were pretty much prepared about it, bought extra safe condoms and lube + he pulled out before he even came. Idk, paranoia is getting the best of me and i don't know whether i should take plan b or not. PLEASE HELP ME
