Bed bugs? (Delco, PA)

I've been finding these little guys for years. I've never seen a colony, nest, or eggs. It's mostly just one or two of them, I've seen at most five fairly spread out on one day. The bugs mostly crawl on my windowsill, curtains, or sheets. I don't think they are bedbugs as I haven't gotten bites but idk. I won't lie, my room is pretty dusty, messy, and hasn't been cleaned / vacuumed as often as it should. Is this a hygiene problem or are they just there? Sorry there's a lot of questions and I'm just rambling but you can just answer what bug this is and I'll figure out how to get rid of them from there.
