had sex on the last pill, with a little condom mistake

so me and my bf had sex when I had my last pill, he was getting upset with the condom because he put it on wrong but then put it back on correctly,(there was no holes and he pulled out so all the cum was inside it) but I'm scared shitless that I'm pregnant... again I'm on birth control and I took my last pill, am I till ok? am I gonna be ok? I've been crying and not eating for 2 days and looking up stuff made it worse... what should I do...😭
