Have you or someone you know gotten pregnant from precum?

This is out of pure curiosity. This month my husband and I had unprotected sex on my ovulation day. He pulled out, I saw it, we’re all good. I’m not concerned about getting pregnant, we’re in a “if it happens, it happens” mindset, so it’s not a question out of worry.

I’m genuinely curious about this, I’d love to hear from people who have lived this!
