Stepped on surgery foot after OATS surgery? Very worried.?

Tomorrow will be my 2nd week after OATS surgery. As I was going on my crutches, I hit a little snag and could only catch myself by putting my surgery leg down. It didn't hurt, but it's sort of sore, although I think I'm being paranoid. It doesn't really hurt, didn't swell any, but I'm still worried sick. What are the possibilities the bone graft moved? I think I'm being paranoid, but you can never be sure.
