Next steps for suspected bed bugs?

I woke up with bites yesterday that I am almost 100% are bed bug bites and more today. I did stay in a hotel about a week and a half ago and my husband doesn’t have any bites. I am obsessively checking our mattress but I can’t find anything. What are my next steps? Do I just watch for more bites and keep checking our furniture, or should I call a pest control company preemptively?
