I went to a first glimpse place and found out at 14 weeks

I found out around 14 weeks with all 3 of mine.

I think it depends on where you are and what your options are.. you can either find out starting around 10ish weeks with blood test, some 3D/4D ultrasound can determine as early as 13 weeks, drs office typically do Anatomy scans between 18-20 weeks.
I’ve opted for an elective ultrasound at 16 weeks with a 3D/4D place (they do it as early as 13 weeks, but I feel more confident that I’ll get a definite answer closer to 16 weeks).

Found out my 2nd was a girl at 14 weeks and our 3rd was a boy at 13 weeks + had bloodwork too

10 weeks via blood work

20 weeks anatomy scan

I found out at 18 weeks with ultrasound but I think you can find out sooner if you pay for it or if your insurance covers it

I found mine out at 15 with ultrasound

13-15 with a blood test 16-whenever usually for ultrasound.

20 week ultrasound
