I was 16 weeks in April when we took a 12hr road trip from CO to TX (900 miles ow) and back in 10 days to see if we like the area. We drove straight through at night, since we have 3 other kids and wanted them to get as much sleep as possible. Stopped 3 times for gas and pee.
Will actually move next weekend and this time we both have to drive a vehicle. We will attempt to drive through the night again but don't know how far we will get since we can't swap. It's what you are comfi with. This is my 4th and we have done many roadtrips while pregnant. If I stop every 2 hrs I will feel as I will never get there...
Drink lots of fluids. Good luck!
you can do it!
