Slightly on the verge of freaking out.

Okay, so I was just laying in bed, and it was one of those nights where I'd kinda play with myself a little, until I felt a hard, little bump on my labia near the opening of my vagina. It didn't hurt at all until I poked it and tried feeling it a little, but even then it didn't hurt bad, but now that I know that it's there, I sorta feel it. Has anyone ever experience something like this, or even remotely have an idea of what I'm talking about? I'm one of those people that always go to the worst case scenario, and I'm actually freaking myself out, I'm a little scared about what it could be 😓
