Have any of you had your due date changed during your pregnancy? According to my last period my due date should have been June 6. At my first appt they did an ultrasound and gave me a June 21 due date based on baby size. I’m curious if this might change as pregnancy progresses. My little sister is engaged has planned a Memorial Day weekend wedding - I will be 37-39 weeks pregnant depending on the two dates and the wedding is two states away😑. Just trying to gauge the possibility of my due date being moved up or are ultrasound dates pretty accurate?
