Unknown Worm

From Edmonton, Alberta: I was away for two weeks and when I came home noticed two tiny worm like bugs on my white bed sheet, and after removing them I found a third smaller worm. I looked up carpet beetle larvae and they did not match the images (they lacked rings and instead were a uniform dark brown/rust color). They moved like an injured inch worm. I squished them in toilet paper and threw them in the toilet before I thought to take a picture. I’m not from Alberta so not familiar with what is and what is not normal for this time of year. Any ideas?
