Herpes Doctor

I gave a guy oral sex two days in a row and within 2 minutes after the second day, my lips felt numb and tingly. About ten minutes later I looked in the mirror and on my inner bottom lip, i have a few bumps, and my lip is red. It's about two hours later now, and the bumps are still there but the tingling has started to fade. I am worried I caught an std such as herpes, but I know that symptoms don't happen that early. My partner says he's clean, but I am afraid of what is happening. Am I worried for no reason? Or should I definitely get tested? If so, what should I ask to be tested for?
