FUE grafts at 42 days are stubble, same length since FUE. Is this normal?

I had 2200 grafts placed 42 days ago, frontal third. There is a little big of shock loss, and the grafts feel like stubble. I had PRP done as well , and was told sometimes with PRP hairs will not shed and go straight into growth phase. The hairs don't seem to be shedding, but are still same length, not really growing. Was told this is normal?
