Ice Pack Concern Post Op

So the day of the surgery, after I got out, I had made the mistake of ice packing my graft area. I was very careful and gentle when applying the ice pack. I never rubbed my head with it, just gently pressed it to the grafts. After doing research, I am reading to never touch grafts with an ice pack, and its only for the forehead. I'm wondering if I possibly dislodged any grafts, or the cold damaged them? I didn't experience any bleeding due to the ice pack, so hopefully not. Any input as to whether I ruined my grafts?

Thanks
