Not bleeding on my period??.... What!?

Today, I woke up at 6:48, felt wetter than usual. I ran a finger down there and I had a lil bit of brown discharge. I went back to bed. Then woke up at 9:36 checked and saw brown discharge, with a lil bit of red blood. I'm 12 yrs old, I'm still a virgin, so I know I'm not pregnant. And Ik that discharge is normal when you're starting. But its now 3:22 in the afternoon. I checked again, and there's no blood down there. Only black/brown discharge. I tried masturbating a lil as well, to get some blood out, still nothing, I even tried to push some of it out on my own, nothing's happening. Am I okay? I feel like something's wrong.. Please comment below what you think is happening.
