advice needed! potentially big baby

Rachel
Hi ladies, I am 32 weeks today and have been referred to see a consultant on Wednesday. 
The reason for the referral is that I am measuring big on 2 fronts. I went for 2 private scans (I'm based in the U.K.) and was told both times that I was measuring ahead. At the second scan I was measuring 31 wks 5 days at 29 weeks and 6 days. 
So almost 2 weeks ahead.
I didn't think much of it as I appreciate babies Vary greatly in weight.
At my midwife appointment this week by funday height was wayyyyyyy above the 90th centile. Which has prompted the referral and a growth scan.
My midwife had neglected to plot my 2 previous measurements so we only have this one to go off. I have felt big the past few weeks and haven't felt great, nausea, tiredness, aching hips/pelvis etc, This is my first baby so I imagine it's just part and parcel of pregnancy.
I am not concerned about where this may end up. C section, induction, etc aslong as the baby is healthy. He is my only priority.
Has anyone been through anything similar? Any advice would be much appreciated.
Love to you all
