Military prenatal care

OMG.... I can't believe I've been waiting all this time for an ultrasound (11 weeks). And went to the doctors today for my appointment to answer the same questions they sent me home with a packet to answer. I thought they would at least do and ultrasound to make sure my dates matched up. One of my friend told me her first ultrasound wasn't until she was 18 weeks. Is anybody else military? When did they do your first ultrasound?
