Remember 40 weeks is just an average; some come earlier, and some come later. My first one was born on this original due date, the ob/gyn had moved it up a week because of the baby's size, but I knew when I got pregnant so I was unsurprised. My second was over a week overdue, so 41 weeks.
Hang in there. They come on their own schedule, and if nothing is wrong, don't worry about it.
With my second one, born in Texas in August; I was ready for him to come out by early July. I have never been so hot in all my life. Walking to the end of the driveway would have me in a full sweat.
