So I’m 5+4 pregnant, the post we are stationed at is only a clinic so I got a referral to get seen off post, but the problem is I am going home while my husband is in training and won’t be back until I’m 11+ weeks... I had a miscarriage in December and want an ultrasound done to ensure things are okay before I’m out of my first trimester, but is it possible to get it done at a civilian hospital while home and TRICARE cover it??
