Whats your babies heart rates been your enitre pregnancy
My little girl so far has been at 130-140 for the heart rate. my son I wanna say was around the same maybe slightly higher. can't wait for you to find out and let us know how exciting :) my friend found out gender at 14 weeks a girl ....but a month before due date she found out it was actually a boy lol. an ultrasound tech I met with 20 years experiance told me it can take up to 24 weeks for the testicles to descend. I found out at 17 weeks I was having a girl and sure enough i've had 6 techs confirm it. (I do ultrasound OB modeling) sound like your person has been right on the money before so thats good. i think experiance and a cooperative baby is always a good combination.
It has nothing to do with the babys position and the experience of the tech, the baby is not developed enough at 13 weeks to tell. Some people may think it is possible at 13 weeks because when they get another ultrasound later in the pregnancy is the same as what it was earlier think about it it's a 50 50 chance so it's not unlikely that they can guess it but at 13 weeks its only a guess and not an acurate one. I delivered my baby still born at almost 18 weeks and it was a tough call then and we were looking directly at her and not thru an ultrasound.
