i’m so mad at myself :(

i’m on the combination pill which I take perfectly and have for nearly a decade. I had unprotected sex 2 days before my withdrawal bleed then (had my bleed on time) and once 5 days ago (first day of active pill in new pack) using withdrawal method both times .. i’m giving myself pregnancy symptoms because i’m that F paranoid and so upset with myself I ALWAYS make my bf use condoms. I still have another 2 and a half weeks until my next bleed and I can’t live with this anxiety for that long
