Ladies on the mini pill...

My son is 10.5 months old & ive been EBF since he’s been born. I haven’t had sex since my son was 3 months old because me and his father broke up and I’ve been single since. I’ve been talking to an old friend that I’ve known for years and we’ve been hanging out. Well we ended up having sex last night. I track my periods and everything and of course I’m in my fertile window and I forgot to take my pill yesterday 🙄 so I know this is a very general question but honestly.. how likely is it that I could have gotten pregnant?
