Hymenal tags

I just noticed this bright red skin hanging out of my vagina and I don’t look down there that often but I feel like I would have noticed haha

Anyway I tried googling it and Hymenal tags came up.

I still don’t understand what this is and if it’s harmful

Anyone else experiencing this

I am 4 months and haven’t had sex yet and don’t masterbate.. did some research and they said could also be caused by those things and tight underwear and tampons but I don’t have that either so very confused
