My bub was 3/5 from 28 weeks and I had her at 40+2. My OB wasn't at all worried.. Or not that she let on anyways! I was a little further a long, but only by 2.5 weeks and it made no difference to me.

I Hope all goes well for you. Don't worry about something that may never happen and something you can't prevent. Stay calm and take good care of yourself.
