Thank you ladies! I appreciate the advice. I heard our winter here in WI is supposed to get pretty bad so hopefully my car can make it down lol.
Bring copies of all your medical papers and pregnancy stuff with you just in case, make sure your stop every 2 hours to walk around and stretch, and don't stay still for too long because you could get varicose veins from pooling blood, but other than those just make sure your comfy :)
Also just as a precaution, inform your ob that you plan to travel.
I agree with the comment above. Pillows snack and drinks. Make sure you are able to recline your seat also. I just recently made a long road trip but I was 35 weeks. I was uncomfortable as can be! I was having contractions too which made it worse. And because of the backseat being full of luggageI ccouldn't recline on the way back. I wish I could have..that would have helped me relax
Bring pillows and a blanket, lots of snacks and drinks, and sleep during the trip as much as you can. If you're suffering from nausea still bring puke bags lol. Good luck and enjoy your trip. Be safe!
