So I'm not necessarily the most patient person in the world and I'm wondering what's the earliest that I can find out…

15 weeks thru blood testing

I'm not patient either. 15 by ultrasound but too many variables so they check again at 18-22 weeks. I found out at 17 with my daughter via ultrasound technology same day I had my genetics testing done. I found out this pregnancy I was having a little boy at 14 weeks via genetics testing and confirmed via early anatomy scan at 16 weeks.

14 weeks through ultrasound

13 via ultrasound and then confirmed at 21 weeks (or close to that) & then again at 23 weeks or so.

I found out at 15 weeks through ultra sound @damire0306

If you have the NIPT test, you can find out as early as 11 Weeks. It's very expensive if your insurance doesn't cover it. I had it but it was covered because of my age.
