a the inside of the labia is itch what do i do

my inner lips have been itchy for a few days now and theres sorta some bumps. i am 14 and i have never had sex nor have i had anyone go down on me or any other sexual activity. there is no weird smell and it does NOT burn to pee. my guess was my tampons because i had been putting them in even though i wasn't bleeding anymore. i am assuming that i dried myself out and thats why its there but i am also very stressed that it could be something else. oh and also i usually have a lot of discharge but right now im having VERY little discharge witch is another reason to think im just dry. ive been putting coconut oil on regularly since this happened

might be chaffing, try vaseline instead of coconut oil
