how far along do you have to be to have an ultrasound done for the gender????



I was supposed to have blood work and genetics testing done in the 9th of Feb but since I already had it done with my son my insurance will not pay it😿
I found out at 17 weeks but I have a friend who found out at 13 doing 3d 4d
just called my doctor and they said the earliest will be 19 weeks 😭😭😭😭
