I don't know what I would do :(

so my bf and I got high a few days ago and had sex. there's no way we used a condom and I'm not on birth control. he said he came in me and I'm so nervous because according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> this is my fertile week and today is my peak day. What are my odds of getting pregnant? I know I was dumb but I'm just curious. I don't wanna take plan b since it fucks up your period anyway
