Preganncy dating can be off either way by up to two weeks. It's not usualy for a woman to go up to 2 weeks past her due date. Due dates are merely a guess.
There is nothing wrong, I was sure of my dates and measured correctly and with my first delivered when I was exactly 2 weeks late. Typically between 1-2 weeks late they will induce you. Sometimes they'll try stripping your membranes first.
i know of women who have ben pregnant for longer than usual and gave birth to normal babies.r u sure of ur dates?if so, u can go to the doctor and get an exam,if neccesary they can induce you.
don't worry
