Blue book

So during this pregnancy Iv been given 2 blue books to keep track. Both books have different due dates and because I didn't bring both the doctors changed the babies due date when his measuring at the due date in the other book and he now insists on the first date saying we couldn't change it to begin with. We were scheduled in for a c-section and now he doesn't want to give me one. Anyone know what we could do to get everything changed back?
