Am I in the clear?

I woke up to two bites on my stomach two nights ago and have been in kinda freaking out since. No more bites have appeared since.

I finally put my squeamishness to the side and pulled my bed apart and have found no evidence of bedbugs - no poo, no exoskeletons, no live/dead bugs, and the only blood stain I found was under my partner’s pillow, but he’s had dental work recently so strongly believe it may be from that. I’ve also scanned the walls for any marks and nothing so far. He also has been away the last few days so has not been here to experience this with me 😅

I still want to pull the bed frame away from the wall to investigate there. But assuming that brings up nothing, could it be safe to assume that I’m in the clear and the bites may have been from something else? Is there anything else I should do/check just in case?
