There is a difference between "term", and "due date". Only 1 in 20 women deliver on their due date.

Your due date is still 4/26/99. The earlier a U/S is performed, the more accurate it is for dating purposes. In particular, a second U/S cannot change your dates. The proper inference is that your baby is a little bit large for its gestational age, though the difference is only 2 weeks, well within the normal error of U/S performed at 29 weeks. Your pregnancy will be term from 4/12/99-5/5/99, 38 weeks to 42 weeks. A normal delivery could happen at any time during that stretch. Your doctor may be able to narrow that a bit based on cervical exam as you get closer, though that is just an educated guess.
