Do i have an ets?

Hey. i’ve only had one sexual partner, it was a girl. I did oral sex to her a couple times and one time she did it to me. I went to two doctors and explained that i had a constant aching, they checked me and said everything looked normal, then sent me to get blood tested and everything was fine. They told me it was vaginitis, then i started a treatment. Anyway, this week i noticed this thing in my vagina, it doesn’t hurt or itch but it’s pretty weird and i can feel it with my hands. Should i go to the doctor? i’m really worried. Today i got blood tested for herpes just in case but i didn’t go to the doctor, just paid for the test They’re gonna give me the results on friday..

just in case it is not clear on the image, i’m referring to this thing over here
