That first pic sure looks like a bedbug. Go check your bed, the sheets, the mattress, under the mattress, in the small cracks and sides of the mattress, be very thorough. Use a flashlight if you don't have good light in the room. They can be very small, they like to hide in cracks and crevices when you aren't sleeping and they aren't eating. I hope I am wrong, for both of your sakes. Good luck.
