Have Redness, White Circles And Pain In Roof Of Mouth. Had Oral Sex. Herpes?

Hi. I recently had oral sex last week. I didn t notice any lesions on my partner s vagina, but a couple of days later, I started feeling some pain in the roof of my mouth. There s redness and some small white circles on the rugae of my mouth. Some are painful (on the right side) and some are not (on the left side). I m wondering if the lesions are from just trauma, or if it s herpes? I didn t have any fever, cervical lymph adenopathy, tingling or chills when this occurred. Thank you Dr. Grief.
