Hi, I Am A 23 Year Old Female, Who Has

Hi, i am a 23 year old female, who has been sexually active, I have always used protection and have not had sex in 4 months. I recently finished a dose of antibiotics for a skin infection which I believe left me with a yeast infection, swollen vagina, red, itchy with a thick white discharge however i had a few cuts in the folds of my vagina lips. Now I noticed i have a scratch on my butt that looks a bit bumpy and kind of scabby. Could this be herpes. I recently had an STI test and it came back clean but im unsure if a HSV test was included.
