A question for military spouses

I’m currently 11w 2d. I have not had an U/S yet nor has it been scheduled. I do have my first “appointment” scheduled, but it’s only blood work and paperwork, and then a scheduling for the U/S. How far long were you when you went, to a military hospital, for an U/S? I know it’s the military and I know how they work. 😒 they have to have a good enough reason, other than your concern, to really work with you.

When do they normally schedule a U/S? And do they do blood work for diagnosis/gender?
