Is this a bed bug larvae/nymph. I found it on my bed. I didn’t see any other trace of bed bugs (molts, blod, debris). It’s really small and light coloured. Head and bottom seems to be darker. It looks really different from different angles. One is in backlight. There is also a small grain, I wonder if it is an egg or something. So is this bed bug nymph or some booklice-type of thing?
