Ultrasound tech can't find sex Currently 22+1. I went in 2 weeks ago for my 20 week screening. My baby was bouncing around like crazy during that day, and the tech couldn't get the images of heart or sex of my baby and set up an appointment for me to return in 2 weeks to finish procedure. 

Today I went in, and after the tech got the images of my baby's heart, moved the screen to me, shows me a foot, arm, and the head. She dismisses me to change, and I asked her about the sex. She told me she couldn't find it after doing some "digging". 

I am pretty bummed about this, and my husband is very upset. Should I make another ultrasound appointment? When should I expect to find out my baby's sex?
