Discoloration and white bump on vagina

hi- I've noticed that i have some discoloration on my labia and it's been there for a while. i also noticed about a month ago that I have a white bump on the same side with no pain/itching anything. any idea what it could be?

sorry i thought the photos uploaded with the post

cpuld be a sebaceous cyst, if been there for a month no changes definitely not std related

perhaps go to the doctor anyway, i doubt it is anything serious but good to be safe
