How big was your fetal pole at 6+5

I got an ultrasound at 7+1 and the fetal pole was 5.93 mm long. I don’t speak the same language as my doctor so she couldn’t tell me anything. I googled and it said it should be around 6+5 which is three days behind but I want to check what everyone else’s were. And if so should I worry about a 3 day difference? Heartbeat was 119.
