Could I have damaged my week-old gum graft?

I had a gum graft done a week ago. The "bandaid" fell off 5 days later. I was brushing my teeth last night and accidentally hit the site of the gum graft with the hard part of my tooth brush. There was quite a bit of bleeding but it stopped shortly after. There is now what looks like a blood clot under the graft and I'm worried I may have detached it.
