Weird discharge

Hey girls, so my story maybe a bit gross but I don't know what is wrong with me. So I was in my bathtub and was masterbating with the back of my back scrub brush and when I was done a discharge came out with what I think was blood in it. Has this ever happened to any of you? I also want to note that I lost my virginity a little less than a year ago and haven't had sex since.
