What is this? PLEASE HELP

In late April I got UTI like symptoms, i took antibiotics for 5 days and was fine. after 2 days or so i felt very itchy, i examined myself and found papillae lumps of my vulva. the doctor said on the phone that its a yeast infection, normal reaction to antibiotics. i took an antifungal cream for 5 days, the discomfort went away but I still had the bumps. Yesterday, i felt very irritated and itchy, i examined myself and found more papillae, my vulva is red and some parts like the clit were swollen, and there white discharge, cottage cheese like, but no smell. I got STD test in April and everything came back negative, however I found out that herpes and HPV were not included in the panel. I am 21, only had 1 partner and he has no symptoms, did not have intercourse since April. I wanna know if this is my yeast infection still untreated or triggered or something else. Please help I am very scared.
