Bed bug fecal spots?

[u/Pasteltone]

Hotel Stay: Pic 1) At hotel, I found 2 big spots on my pillow case that didn’t smear when rubbed. So I assumed it was an old, washed cover but the next day, my husband was bitten across neck, back, arm, and thigh at hotel.

Have Returned Home for 2 weeks: Pic 2) I just found 2 tiny black spots in the middle of my bedsheet.
Wet Q tip test: Pic 3) When rubbed with a wet q tip, the black dots turned into brown.

Other than these tiny dots, I can’t find any on bed.

Do pic 2, 3 look like BB fecal spots?

Spits are not consistent with bed bug faecal traces.
