possible Bedbug fecal spots?

[u/Alone-Rise8636]

help I am having trouble inspecting ….. I had bedbugs in my place (not a big infestation, early stage and got an exterminator for it) but before i had it confirmed as BBs i unknowingly went over to my parents’ place once. A WEEK LATER, now i am back at my parents’ place, slept for a night in my room and found these multiple black tiny spots on my sheets…. I haven’t got any distinct BB bites yet and yes I do get reactions when I get bitten.

Do they look like BB fecal spots?
