Help!

We just found out last week that my husband is deploying in January for 6 months. Therefore, he's going to miss the birth of our first child. We are originally from Illinois but are stationed in New Mexico. To avoid being alone I've decided to go home during his absence & be with family. So I need yalls advice! I'm driving home in my car & I'm also taking the dogs home... I won't have much room but im thinking all I'll need is clothes & toiletries. My problem is....I'll be home for 2 seasons... Pregnant & then 4 months post pregnancy. (Winter pregnant & summer not pregnant) What kind of clothes do I pack? Do I just need to plan to buy when I'm home? I don't know what size I'll be! Help!
