That’s weird I’ve always been told by my OB they go based on your early scans and they will not adjust your due date afterwards. Like with me my son is measuring a week and some days ahead which actually puts him at a 10/31 due date not 11/9 but my dr won’t move it because she says the early scans are the ones that are correct.
@laniejay, yeah. I had to change OBs and they had to relook at the ultrasounds and found out I was actually a week ahead from what my previous ob said and it looked like they were misreading or something
