Actually, you are really only about 1 week and 2 days ahead. That's not bad at all. I was told that as long as you're within 3CM, they don't get concerned.
As of Friday, I was measuring 35 weeks myself, although I was only 33 weeks and 3 days. But, honestly, I think the midwife that I saw on Friday measured differently than the doctor I had at the last appointment. She took the measurement from the center of my pubic bone, whereas I think the doctor took it from the top. So, someone is doing it wrong... Up till I saw her, I was bang on-time.
