35 weeks measuring big

Risa Marie • Wife. Farmer. Momma to Elsie Jo & Sadie Mae. Cat Mom of 2.
i had an appointment yesterday at 34 weeks +5 and my baby measured 37 weeks with a tape measure on my belly. two weeks ago at my doctors appointment she was measuring 35 weeks. all of my previous appointments she was measuring right on. anyone else have this and the baby came earlier than their due date or will my baby girl just be big?
