I'm on the borderline with the enhanced maternity package at work (will have worked there for 1 year in the 15th week before EWC - can't quite work out - think I'm ok but not comfortably so). How flexible are doctors with due dates?!!! Would be good to be 5 days later than I think I actually am if you know what I mean. Haven't yet been to see doc - appointment later this week... First time pregnant so any advice gratefully received
