Help!!! Can't tell if sores are getting better or worse

I went to urgent care two days ago, and they gave me a herpes test for types 1 and 2, but both came back negative. I followed up with my PCP, and she said she wasn’t sure because the tests can be wrong, so she continued me on antivirals. I, personally, do not think it’s herpes because they were triggered by an autoimmune disorder flare up I experienced after my second moderna dose, but I’m not sure what other forum to put this under. The first picture is from two days ago, and the second is from this morning. To me they look way worse, but I don’t know if that’s just how genital sores heal.

Upon Further Investigation I think I’m dealing with aphthous ulcers just kinda doing what they do in case anyone has anything similar lol

have you had a blood test for syphillis?
