Wrong due date or big baby?

As

Has anyones due date been just completely off or did you just have a big baby?

I am technically “30 weeks” but baby has always measured bigger, now today she’s measuring 35 weeks and they are checking my fluids on Thursday.

She went from measuring 2 weeks to now 5 weeks difference.

Idk what to even think like besides wait on this appt.. just curious to hear others experiences. I’m interested to see will she come sooner or closer to the due date or will they induce..
