Scab fell out today with hair in it, is it a hair graft or just the shaft? (photo)

Hi, my name is Leonardo, im portuguese. I ve done a FUE in February and im a little worry because a lot of the scabs have not fallen yet.I alvo have dry and white skin at almost 3 months. Maybe i was a little too much careful while washing my hair, i don t know. Anyway, i want to ask if this is a lost graft or is just the shaft. Thank you.
