Masturbation and blood

Hey guys I'm just little afraid about what happened just some minutes ago I was in bathroom and taking a shower so I decided to have some my time and start rubbing my vagina but I decided to put something in it too I've used my fingers and tooth brush before but from front, I tried to put toothbrush handle in my vagina from back side and start thrusting in and out it was completely normal until I saw some blood and my wetness on brush I got scared and I didn't even get finished. So I started washing my vagina thoroughly and checking some blood but no there was not any blood and no pain. I'm just confused what was that? I have periods in 9 days so I don't think it was my period blood. I'm scared I don't want to loose my virginity yet. I know I can't loose virginity until I have sex with someone but still Please can anyone tell me what was that? Why it happened?
