Big baby?

I am 34 weeks pregnant with my second baby. My first daughter was born on exactly 39 weeks and weighed 7.12. Last week at my 33 week check up I measured big so I had a growth scan today. This baby is actually measuring at between 35w4d and 36w. I have a repeat c-section scheduled for dec 2 but I am so worried she’s going to be HUGE by then. Have any other moms experienced this? Did they take the baby early if not was the baby as big as they predicted?
