So I know they are unreliable because of the genital tubercle, but I really want to compare all of them we can gather for fun! I cannot find anything online that compares multiple fetuses via ultrasound at this gestation. Obviously, cause it is unreliable, but some claim that they can tell, and others, say no. So post your 12 week potty shots and then lets update when we know for sure!
This my my 12 week 4 day potty shot and the tech said that it looks like a boy. Also based off of the nub too, but this is just potty shot fun.
