My Septum Cartilage Appears to Be Exposed Within my Nose Following Septoplasty (One Week Ago). Is This Normal?

My healing process seems generally in line with the usual experience. However last night I took a peak into my right nostril and noticed a white circle the size of an eraser butt-end about an inch and a half into my nasal cavity. I understand this is where the incision is usually performed during septoplasty - so I'm not sure if I should have a cause for concern. I did however notice a stitch fell out around the 5-day mark. There is no excessive bleeding.
