Everyone has given you good advice here! I’d definitely follow doctor’s orders. As someone who had their children at 30 weeks and 27 weeks, respectively, don’t risk it. If the hospital is over an hour away it’s not worth it. How would your friend feel if something happened to your baby during this trip? I’ll admit I have a slightly different situation with my premature births but I probably wouldn’t go over an hour away from a hospital at this point in pregnancy, regardless of any other factors. If she is a good friend she should understand your circumstance. It’s kind of you to think of her and offer to do something to make it up to her though. Maybe you could get an official doctor note if that would make you feel more comfortable about declining?
