Chances of pregnancy with pull out while on MINI PILL

K
Hi! I know there's a lot of these types of questions but I'm on that waiting period and I have general anxiety so I had to ask.
I'm on the mini-pill, on and off last June but have taken with Near perfect use the past week. Sunday I had unprotected sex but he pulled out although he came on my bum. Sunday is Cycle Day 9 for me and I do track my ovulation for fun lol so far haven't ovulated so it's been about 2-3 days.
I know the mini-pill doesn't prevent ovulation 100% of the time so I'm getting anxious that there is a chance I can get pregnant from that. Any insights or opinions welcome please. It's hard to find threads specifically about the mini-pill.
Thank you!!
