5 Week Ultrasound?

Hey! I just found out I'm pregnant after a miscarriage in December of 2017. I'm on Tricare so they referred me to an OB. They set up my appointment with her when I am 5 weeks for an ultrasound and what not. Is that too early? Once I'm 8 weeks I'll be going home for 2 weeks before my husband and I move to North Dakota. Once at North Dakota I'll almost be 15 weeks so I know I need to see a doctor before I leave here. I just don't want it to be a waste.
