Personally I would be uncomfortable going that far when I’m about 38 weeks, but it also depends on how your feeling. On my first pregnancy I struggled with a lot of back pain and I wasn’t physically able to sit in a car for long periods, so this kind of journey would not have been possible for me.
I’m doing a 6hr work trip next week, 3 hrs there, then in the office for a meeting for 4-5 hrs then driving 3hrs back.. I could book a hotel but I have antenatal class which I want to get back for and I don’t sleep at all in hotels etc I’d rather be in my own bed. I will just making sure I stop every 1/1.5 hrs, drinking plenty of water on the way, walking around loads when I stop to reduce swelling etc. I’ll be 33 weeks. Hoping it’s the last time I need to go before maternity leave!
I didn’t know there was a limit! I think its fine as long as you’re comfortable and stop for regular breaks x
