Are these bed bug husks?

Hi everyone, I was recently exposed to bed bugs in my apartment (a neighbor had them and they started coming over through the wall) and I ended up moving out.

Long and short of it is that I threw out the high risk items (couch, bed, bed frame, desk) and dried every piece of clothing I own on high heat for at least an hour. All my books and miscellaneous items are in sealed boxes for the time being.

I feel good about the steps I took, but of course a concern of mine is that anything followed me to my new place. I recently found these three strange shapes on my bed though.

Do they look like bed bug husks to you? The shape and color looks different to me, but I’m a bit perplexed and super appreciate any opinions. Thank you!!
