Should I be concerned?

Hi, we have a girl berner that’s a bit over a year going through her second heat cycle. It was a bit of a surprise to us that she went into heat about 3 months after her first one, but we heard it can be variable. However this one is significantly heavier and I’m starting to get a bit worried. This is the amount of bleeding in the last 12 hours and some of that time she was outside without her diaper. Do I need to make a vet appointment asap? Or is this a variation of normal?
