Pimple like bump on Labia minora, is it herpes?

I had unprotected sex with my bf on july 17 and a pimple like bump, like a boil appeared on my labia minora on august 1st, it burned when pee ran over it but I dont know if it ulcer like a herpes sore pretty sure it did pop. Got it checked on the 5th and am waiting on blood test they didn't swab it cause the nurse said looked like a small blister. when I looked I dont know if it's the same one but a small bump is there. Bf doesn't have anything but we are assuming asymptomatic. What else can it be other than herpes?

someone please help.

i have the same thing please update me with what you have im so scared
