So I just found this out from two of my lady friends they both are around 22 weeks now but when they where 11 and 12 weeks they asked the doctor when the doctor was taking blood to test the babies for down syndrome and other stuff, if they can find out the gender of the baby through the blood work and they all say it worked so I'm going to try it I'm doing the blood work and going through ultrasound of course but I wanted to see who was all doing it to or if anyone has done it already let me know if it worked for you girls thanks hope this was helpful for the lady's who didn't know this either :) can't wait !!
