I did that around 31 weeks, had to pee a lot but it gives you a chance to walk around a stretch a little. Make sure you keep up with your water intake (hard to remember on road trips sometimes). I would also highly recommend some knee high compression stockings to help with any swelling and reduce risk of blood clots, you can get them at Walmart or Walgreen's or any drugstore.
Have a good trip!!
I'll be doing the same :-) Except 24 hrs! It's going to be very uncomfortable (more than you think), I know this because I did it a few months ago at just 14 wks & it was already miserable. I've driven across country about 8 or 9 times & it's never felt as cramped as it does with the babes! Can't imagine what it will be like at 33 for us!! Lots of stops will help hopefully!
Yea i know many people that still travel than.. If you are not going to be gone for a couple of weeks but a week or so.. ANd the doctor says its ok there should be no problem
