An easy indication that grubs have hurt the lawn is that it would be lumpy.

Also, once they damage the lawn, it's over, no point in treating until next year. You can begin the repair, like over-seeding and putting some stop-soil down.

It could be that you have a fungus problem, like Brown Patch.

Upload some photos, and maybe we can help pinpoint it.

It's to early in the season for grub damage. Fron what your describing, it sounds more lime Brown Patch.
