it normally depends, i didn't find out till 20 weeks. they can do a blood test to find out sooner. i never looked into it though. for the ultrasound the schedule between 18-20 weeks at least at my doctors office they did.

I'll be 13 weeks in two weeks and my next apt is on the 28

I found out at 13 weeks. guess it depends if baby has their legs open☺

Hopefully they can tell me at 14 weeks too

I found out at 14 weeks:)
