How long at dilated to a 3?

Katy

With my first baby 3 years ago I went for my 36 week apt at 36.5 weeks and was dilated to 3 then had him the next morning. This time I went to my apt at 36.5 weeks and was dilated to 3 again. How long have people been dilated to 3 before actually having baby? Could it still be a while (1.5-2 weeks)?
