Is this punch biopsy site infected or just not healing? (Photo)

I had a 6mm punch biopsy performed for a tiny mole on my ankle three weeks ago (came back benign). Three external sutures were put in. The nurse removed the stitches but I said it didn't look healed. She covered it with steristrips. It's been three weeks and the steristrips finally came off today and it looks like its not healing to me. The office won't be open until next week so I can't call or see them for a couple of days. It doesn't look like any biopsies I've had before.
