in desperate need of help 😭😭😭

Okay so I had sex on my 2nd day of my fertile week. My fertility score was a 7.5 and my ex came in me. What are the possibilities of me being pregnant? Do you guys think it's more likely or less likely since it was on the second day? He didn't say he did until yesterday and It's too late for a plan b and I just need to know if I should prepare myself for a BFP or if I'm fine. The situation my ex and I are in isn't a good situation for a baby to be involved with. So I'm hoping I'm not because I know what I have to do if I am pregnant 😪😔
