What to do

Hey everyone! So my boyfriend and i had a really nice sex session. With protection! Even with condoms he always pulls out in case. THIS SESSION however, when he pulled out, the condom was off and he came on himself. Im going to go get morning after pills just to be sure but is there any other steps i should take to prevent pregnancy? This is also the first time a condom has came off while we had sex and we have been using the same brand every time.
