help! just found a bump! *pictures*

i was putting on underwear and felt a bump. i dont think it was there yesterday. it’s painless, smooth, and does not have a white top. i was thinking it might be a cyst? i havent had sex since december so im not sure if it’s sex related. please help!

i had one a few days ago its just a labial cyst /spot it went down after about 4 days

hard to see from those pics.
