Second baby at 96th percentile- anxious about birth

I am due to have my baby this first week of April and feeling very anxious, this is our second baby and with my first I had an emergency c-section due to meconium and fetal distress with my first.

On this second pregnancy I was very determined to do a Vaginal birth after c-section due to wanting a faster healing recovery post partum and wanted my other subsequent pregnancy after to be normal.

I never had GDM with my first and he did weigh 3.9kg at birth though and now with this second baby my glucose test was normal. My midwife thinks I might have late-onset GDM and am redoinh my glucose test this week due to baby jumping up in percentile from 70th to the 96th percentile.

My midwife is very supportive with my birthing plans but now am feeling very anxious about doing a VBAC and knowing about my baby being on the 96th percentile. Also, to add to the stress my first born was sunny side up during labor and really gave me a hard time lol and now this second baby is also showing up sunny side up on my 34th week scan.

The anxiety is just making me want to go for an elective c-section but my heart was really set on a VBAC :(, any momma's out there who had a similar experience?
