found under the mattress, one appears to be dead. there were other moving ones we also saw under the mattress, but couldn't capture. (middle image is a different bug from the other two). we are thinking it is bedbugs, but unsure, as it seems a lot smaller than all the pictures online?

caused an itchy, splotchy rash across exposed arms and legs, and a sleepless night last night. any help would be incredibly appreciated this is genuinely my worst nightmare and i am terrified
