Possible bed bugs 😭😭

Okay so two days ago, Wednesday it was midday & I was trying to take a nap I kept feeling a bite on my arm so I got up & looked but didn’t find anything.. I tried to fall back to sleep & then legit killed a mosquito biting my leg.. I’ve had bed bugs before so I’m paranoid & that’s like the last thing I need is to pay for an exterminator... anyways so barely last night I noticed the bites I was feeling on my arm are in a small cluster there’s like 6 bites... it has to be bed bugs right? I checked everywhere I found nothing.. none of my family has had any new bites since Wednesday. I’m so legit scared I just wanna cry.
