Small amount of semen

Has anyone gotten pregnant from a small amount of semen entering the vagina? We had sex but the way it went he didn’t exactly cum inside of me but we put it right back in within about 10 seconds most likely less 😅. Yes, I’m TTC. Also this happened on ovulation day. Just not sure if this would be enough. Another detail (sorry if TMI) but once we put it right back in we did so for about a minute. I’m so worried that won’t be enough. Thanks for any insight into your experiences with a small amount of semen.
