HELP!!!

So last night after I was done showering, I went to the bathroom and experienced some discomfort when peeing. I cleaned myself up and took a closer look at my cookie and to me it looks like I had a very small red/pink bump on my vaginal lips at the bottom of the vaginal opening. It’s painful to the touch but i’m not experiencing any itching, however this morning, the discomfort isn’t as bad when i peed, any ideas what it could be?
