I know how you feel! I'm 40+4 today and not expecting to go anytime soon! DD was born at 40+3 and DS was born at 41+5 so I've never had an 'early' one. One thing that does help me is planning things for a week or so away.. Getting hair done, visiting beautician, massage etc. Then you have something else to focus on other than the birth of your baby. I also really like the idea of my baby choosing his own birthday. I always wonder when it'll be!
It's so hard to remain positive at the very end, especially when you're so uncomfortable and even sleeping is a drag! But you really won't be pregnant forever and you'll be holding your little baby in only a matter of weeks now, that's not long at all!
All the best! Can't wait to read your BA x
