trusting the pill?

I have struggled with anxiety my whole life. it’s just something I have to deal with, so that’s probably why i freak out like this, but some reassurance would help. I just recently became sexually active this year with my bf and I got on the pill and waited a month before we had sex without condoms. I get anxious every time waiting for my withdrawal bleed even though i take the pill religiously and have never even been one minute late. lol. this month we did have sex 4 times and used condoms each time, but there is a possibility that the condom broke once (not sure) so that would mean he came inside of me. that scares the SHIT out of me. like I said, I take the pill perfectly. how can I ease my mind and relax? my withdrawal bleed should come soon. I don’t want to make it even later cause i’m stressed.

thanks so much
