Do i tell him??

we are not really on good terms cause I think he wanted it casual but never told me. We had sex on new year's and he told me he never pulled out and hoped that I had the morning after pill "for my own sake" cause he'd be a shit dad.. my period is due at the end of the week but I couldn't get the MA pill..

Idk if I should talk to him about it?? I'm so anxious..

EDIT: this wasn't planned and only the second time, we had protection for our first and we discussed boundaries. But this time it was disregarded..
