Should I be concerned about my bone graft and how it’s healing? (Photo)

I had a bone graft this past Monday. I’m taking antibiotics 3 times a day and doing a warm salt rinse twice a day. I’m concerned at the look of my gums and how far down it is, maybe one of my stitches is loose? Also, a little white has come out. My surgeon isn’t open until Monday so I was hoping to get some input. Thank you for any information or insight.
