Should I be concerned?

So me and my bf/ex were having sex the other day and like normal we were having fun (with a condom) and then we switched to anal and he figured we will just take the condom off after to limit any type of infection I may get if we were to go back to my favorite *hole*. So we took off the condom and I ended up giving him a blowjob for a long ass time (and im pretty sure there was precum) and then all the sudden his ass decided we were going to have sex again (I totally blanked on the fact there was no condom anymore) and then all the sudden he pulled out and came on my face..

So you think I should worry about getting pregnant?

Like I just got off Devil Week (shark week) like 4 days before..
