It is difficult to tell if you have shock hair loss or over-harvesting of the donor area. Over-harvesting would be unlikely if your original donor density was normal as shown here (see: https://newhair.com/donor-area/). However, if your donor density was low, then 3000 grafts could have exceeded your maximum number of grafts that can be harvested. There is little you can do now but wait and see what you look like in 5 months or so.
