Depends on the dr. I had the same dr. For all my baby's and hes always told me around 21 wks. I tried the chinese calendar this time its wrong. . Its says boy but im having a girl.
At the earliest 15w..most dont find out til 18w or 19w
Its commonly done between 17-20 weeks I was 19 wks when I got mine done and I also tried the Chinese chart it was suprisenly accurate for me it said boy and I'm having a boy but that chart is just mainly for fun good luck though:)
I found out at 15+5 and it was accurate. It also depends when your dr wants to check though
I was told today and im 15w
I was told at 16 or 17 weeks I think
