Pregnant during a CONUS to OCONUS OCS, tips?

Helen • 24y/o Air Force wife💙. MOM to a Feb ‘19 babe and soon to be Aug ‘21 babe!

My husband, 1 year old and I will be driving up to Alaska for a PCS in July and I may or may not be pregnant. What are some tips you would recommend for the process?

Note: this is also our first PCS, and we have two small dogs and a cat that will be traveling with us in a car. We are planing 3 weeks for the trip including stops and vacation time.
