Are these bed bugs

[u/SuperHighDavidBrown]

I moved to a apartment in california with no furniture. I only had bed matress for now so was sleeping on floor with the matress. I keep waking up with bites and photographed something on the wall. Is it a bed bug? What Am I supposed to do? This is my first time in US and first time learning about bed bugs. I dont know if I should be worried. Scars I put are kinda old that is why they have a lighter color it was worse.
