When should I make the appointment

Jess
I'm still in shock those two little lines haven't disappeared.  I am almost 5 weeks but I'm not sure when/ where to make an appointment.  Here is my situation...
Currently my husband and I are temporarily stationed in Oklahoma for a TDY en route and will be in our new base in 6 weeks (which will put me at 11 weeks.)
Should I go ahead and make an appointment before I move? 
I've been taking prenatals for months, and have experienced zero spotting or anything that would cause concern.
