Chances?

Okay so my bf and I got super drunk and we had sex without a condom. He didn’t cum but it was still unprotected. I’m not on birth control, so I took plan b two days later. I haven’t checked <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> since I logged my last period but I realized that I was on one of my fertile days when we had sex?! I’m very scared and I hate myself for making such a stupid decision because i was under the influence but ughhh please help.
