I'm due on December 4th. Would I be overdue on the 18th (start of week 42) Or 24th (last day of week 42)?
I'm drawing a calendar of weeks 37-42 on a posterboard for my shower on Saturday so friends and family can just pencil in their name when they guess LO is due. I figure it's a simple thing to have off on the side and it'll amuse me to check in every day towards the end of the pregnancy.                
                             
        
Re: When are you overdue?
This. I had some complications early on and my OB said depending on the size of the baby we could talk about induction as early as 39 weeks.
