Traveling at 31 weeks 3 days on a 17 hour road trip to see sick mother.

Chelsie
I have received news my mom that jas been battling lung cancer has taken a drastic turn for the worse and is declining rapidly. Im not looking forward to this road trip at all because its going to be just me and my 4 year old daughter because the hubby has to stay home for work. Not looking forward to this trip at all and mixed emotions about seeing my mom in the condition she is in. Anyone else have to deal with possibly losing a parent or loved one while ubber pregnant? I went and bought some compression socks so hopefully that helps with swelling... any other tips for traveling in the 3rd trimester?
