Uhh.. Masturbating?

So I've been on my period for about two days now and when I woke up this morning, I thought it had stopped. So later on, when I was home alone, I masturbated. Eee. So.

I finished up and everything.. I rubbed at first then if angered myself, so after a few seconds of laying there, I feel a gush come from below. So I thought that I had came or something. So I was like oh, that's odd.

And by the way, I'm a complete Virgin, haha.

So I put my hand down there to investigate and when I look at hand, there's blood all over. I layed there for a second, catching the blood because it kept coming. There was something that looked like a blood clot on my sheets but I'm still wondering..

Is it possible I 'popped my cherry'? It didn't hurt one but.

Or did my period just come back?

Help? Haha.
