dark red/ purple bump on vulva

So i first notices this red/purple mark a month or two ago and at first it was small & grey to this size but has stayed this size for awhile. I assumed it would go away, but it hasnt. Google says that it maybe be a vaginal hematoma from pregnancy, but i’ve never had a kid let alone been pregnant. I just wanted to see if anyone on here had something simplistic or knew what it was. I plan on making an appointment for the obgyn soon as well, this is just for the meantime!
