Measuring 5-6 weeks ahead

Hailey

So I went to my appointment yesterday and they told me my fundal height is measuring 36-37 weeks, and I’m 31 weeks. Had to go do the 3 hour glucose test today, and going for a fetal assessment ultrasound next week. They’re thinking I may have excess fluid, plus a big baby, ultrasound will tell. Has anyone else measured this far ahead?
