According to my LMP, my widwife says my due date is June 17, but my first ultrasound measured larger and he put my due date at June 11th which lines up exactly with the two dates of possible conception I wrote down. My midwife says unless it's a over a week different, they don't change the due date. Being sick and wanting the first trimester to be over, of course I'd rather be well into my 10th week than 9w 6d. Anyone have this happen?
