HELPPPP!!!!!

So last night my bf and I had unprotected sex and he pulled out but said to go to the bathroom bc he wasn’t sure if he pulled out in time but I didn’t have to go to the bathroom. I woke up this morning and looked at my eve app and my fertile window ends tomorrow and my chance of pregnancy was 33%. What should I do? We’ve only been dating for 2 and 1/2 months.

Update: I took a plan b pill. I also found out that I made the cheer squad where I’m from (non high school) so hopefully the plan b works if not I’ll be back on for more advice 😬😬😬
