Measuring about 5 weeks ahead?

update:

Went for my ultrasound today, and she is measuring 4 lbs 14oz and everything seems normal.

Does anybody have experience or know what the doctor will usually do if you’re measuring about 5 weeks ahead during the 3rd trimester? I’ll be 31 and 6 and I’m measuring about 36 weeks. They’re sending me for an ultrasound. But does that mean I’ll likely be induced early?
