Lump on my labia [TMI TMI]

I was looking my lower area and felt this huge lump on my upper left Labia. Does anyone know what it could be it’s a little itchy, and I’ve never had sex with anyone, I keep it clean down there but rarely shave (only every 4 months) the lump feels solid but not very fluid filled and every time I brush my hand over it, it feels like it could be popped I don’t know.

Any idea what it could be?
