Baby measurement and due date

MM

Based off my last period I’m due 08/26. But from my dating scan I’m measuring for 09/09. I have very long cycles, theyre 40 days long. So I know that going off my ovulation date the 09/09 due date matches up.

But ever since I was about 15 weeks, the baby has been measuring 2 weeks ahead. I just had a check up today and I’m 28 weeks 5 days and from the measurement from my uterus I’m still measuring 2 weeks ahead.

My original OB retired during my pregnancy so I switched to a midwife when I was 26 weeks. They decided to keep my 09/09 due date even though I’m measuring 2 weeks ahead.

My question is, did anyone else measure 2 weeks ahead almost their entire pregnancy and deliver early. Or did you deliver very close to your due date or were you late??

I’m aware that due dates are estimates and baby can come anytime after 37 weeks. Just looking for some similar stories.

TIA!
