Flesh colored bump on inner lip of my vagina?

I just noticed a have a small flesh colored bump on the inner lip of my vagina and it's pretty sore. It's about the size of a pea. I just went to the gynecologist about two weeks ago and they checked everything and said I don't have herpes or anything like that. They lost my pap smear results so I had to go back a week ago and do it again and they said I don't have gonorrhea or chlamydia. I did, however, have a urinary tract infection and a vaginal bacteria infection but I took pills for both of those and they're both gone. But I have nooo idea what this bump is and I really don't wanna have to go back a third time. Please helpp?
