C.C.
I had a job during my first pregnancy where I traveled all the time. I had horrible morning sickness (all day sickness, really), and it was okay, actually. I just made sure to pack saltines in my purse, and had a bunch of gallon-sized Ziploc bags just in case. :(
Travel during the first trimester is much less challenging than during the last trimester. With my first, I was pregnant in 2002 when the TSA was completely nuts. Several times I had to expose my pregnant tummy for all the world to see, so they could "verify" that I wasn't smuggling a bomb or something. Uggggh. (Like my hugely swollen ankles weren't proof enough that I was pregnant? A$$holes.)
