LMP June 17th, missed period July 14th, got pregnancy confirmed but they won't treat me until...?

August 12th! And that's not even an appointment. My husband is stationed at Ft. Eustis, VA and we have to go to Langley Air Force Base for prenatal care. But they won't treat you until you go through an "OB Cl" at their clinic. So I'm just having to guess my due date and how far along I am. I thought they should've been doing this quickly after my pregnancy was confirmed. To at least see how far along I am? I just hate not being able to know my due date or exactly how far along I am, and I just want to hear from a doctor that everything is okay right now. This is my 2nd child, and with my first we were stationed at Ft. Bragg, NC and I didn't have to wait this long or take cles, etc. Has anyone ever heard of this?
