I have had two 14-day windows within the past three months, and both times I went to a one-month window as soon as I got close to my EDD (currently in a one-month window as you can tell by my EDD history). Pretty sure I've read other people getting at least three 14-day windows before they got good news. I believe once you get a 10-day window then be on the lookout. Otherwise, maintain reserved optimism.Have you received your VIN yet? I got my edd updated this morning from 5/16-5/30. Just curious how long after you fall into the 2 week window does the VIN come.
