Just means your baby is measuring on the larger side of normal, my boy was 95th-99th percentile & when born & was 8lb7oz & sat in the 99th percentile for hight & head circumference. I'm very small framed & had no problem in labour so it's nothing to worry about

my last baby was 7lb 14

I was in the 95th percentile 4 weeks ago lol! I think it means that out of 100 babies born there will only be 10 bigger than yours?? x
