I am losing grafts or is this just normal hair shaft shedding after an FUE? (photos)

I was doing well on POD 6 (Pic 1) but on POD 8 I developed these "cracks" or "valleys" (Pic 2). My transplant doc said this was the beginning of hair shedding. He advised that I wash more thoroughly. I have. Some of the scabs have little hairs with a possible a bulb. (Pic 3). Do they look like shed grafts or just hair shafts? I'm afraid the scabs contracted and pulled out some grafts leaving the barren areas. Can anything be done now? (Pic 4 is current picture POD 13).
