Does this make ANY sense?... Every Thursday I'm another week.. So on Friday (3/11) at my appointment I was 32wks and 1 day, due date still May 3rd. My dr tells me that I'm wrong (never once has told me that with how far along i am or anything), that I'm 33wks and 1 day, and that my due date is May 4th because of it being a leap year. But a leap year would make it May 2nd. And if I'm 33wks then my due date would be like April 28th (40 weeks). >_<
