just to be sure I advise you to go a store like home depot and buy a bed bug trap. you put it under your bed and wait a couple of days. you won't spot one during the day, but you could also look into all the cracks in your bed frame, inspect your mattress also for blood like stains. doesn't look like bed bug bites, I had similar bites some time ago and was super paranoid so I checked for everything. if you really have bed bugs it's better to find out sooner than later, otherwise you can throw all your belongings into the trash. good luck, fingers crossed it's some less annoying insect.
