My husbands family is retired navy and yes its true if she is going to a doctor on base then they may only do 1 ultrasound so they will wait until they know they can find the sexes and everything. Unfortunetly on base care is very lacking. If she wants to get more ultrasounds or anything like that she will have to find a doctor off base but she might not be able to do that just depends on what the insurance says.View Thread
