I had a scan at 31 weeks and was told then that bub was the size of a 34 week old but now I'm close to the due date my midwife says that bub is big but an ok size. She said that our bodies grow babies that we are generally able to cope with in terms of birthing.

I reckon you should try to relax as the reality is until you get to the birth you won't know for 100% and right now looking after yourself and not worrying will help you more. Maybe try massage or other relaxation ideas, I have found these things have helped me when I get worried or concerned.

Goodluck
