Special Blood work at 12 weeks.
Had to wait till I was 22 weeks to see what I was having
I have mine done at 20 weeks
I just had my ultrasound today (I'm 18 weeks) there was no question that its a girl :) I know some drs will do it earlier though.
I found out at 15+3 by paying for an extra ultrasound.
I find out tomorrow ill be 16+4
Im in uk and you can get private gender scans at 16 weeks
I'm having an ultrasound done at 20 weeks but the doctor said it's not 100 percent accurate
