Bump on labia majora??

I’m freaking out a little bit. I found a ball like lump on the inside of my Labia majora a little bigger than the size of a pea. It’s weird it’s like a little ball. It hurts a bit when I touch it. There’s no difference in colour or anything. You can hardly see it from the outside. Obviously I’m gonna talk to a doctor but I wanna know if anyone else has experienced this before. And I’ve never been to the doctor for anything to do with my vagina, never had a pap or anything So idk what to expect. Also how do I bring this up to my mom lol I know that this is something that you don’t have to tell your parents but I wanna but it’s a bit awkward so I also don’t wanna and plus she would be the one who would drive me to the doctor anyway
