Hard lump near vagina

I have a hard lump under the skin, about the width of a pea, but not raised as tall as a pea, near my vagina lip (it’s kind of in the crease between where my leg and vagina meet). It doesn’t hurt or itch. Any idea what this could be? I’ll ask the doc when I go next week, but curious if anyone has insight in the meantime? I’ve never had a cyst, does it sound like a cyst?
