Positive signs to look for after FUE hair transplant

I am exactly 8 days post op. I had an FUE HT. My scalp seems to be feeling more normal than the past 7 days. I still have the hairs in the recipient area from the grafts. I had an unrelated dr appointment yesterday. My blood pressure was slightly high at 140/70 my oxygen level was at 98 which they said was good. I’m wondering if there are positive signs that can be observed this early as I’m told the first few days are crucial. Would it be obvious if you lost a graft? Or damaged it?
