Just that really, and how many weeks did you wish you had worked up to? Assuming that you didn't have a really early baby 
I am just wondering. Would like to work up til 2 weeks til due date, as I keep thinking as a first baby it will be late. So if I took 4 weeks then baby was 2 weeks overdue that would be 6 weeks wasted at home without baby.
Is this unrealistic though? I'm worried about tiredness and backache and all the other unknowns, but I'm not especially active ie. I'm sat at a desk most the day.
Experiences appreciated :)
