HELP!! I need an excuse! Lets get creative 😉

Alright ladies I need some help! I am flying to Minnesota in a month and my husband is driving up a week later because of work.  Normally I drive up and he flies in later so he doesn't have to waste time driving. But because I'll be ten weeks pregnant I don't want to drive 18 hours alone with the pets. I need an excuse to tell my family why I'm flying! I don't want to tell them im pregnant until we are face to face. Help!
