Growth scans and measuring big!

So I had to have another growth scan as my fundal measurements are below the 10th centile and there was no growth within the last 2 weeks.

I'm 38 weeks today and baby is now approximately 7.6lbs😁 and growing absolutely perfectly.

Baby is happy and healthy so midwife sent me on my way and said to let Mother Nature takes its course.

On the monitor it said i was measuring 40 weeks and 6 days which is almost 3 weeks bigger than I am.

I just wonder did anyone measuring bigger have their baby sooner than their due date naturally?

Thankyou!
