Bleeding

hi ladies! i’m a teen, and i use the organicup mini. i’ve had it for about 4-5 cycles, but i haven’t really figured it out until now. i used it all day yesterday and about half of today. i felt myself bleed, which usually happens when i wear a pad, but i read that it shouldn’t happen with a cup, and i checked and i was leaking. i took the cup out and the cup had overflowed, but the blood all over my hands definitely didn’t look like period blood. it was very bright and thin, like it would be out of a cut, and my period blood is usually much darker and thicker in my period. i’m scared i scraped myself inside or something ? idk, i wasn’t sure if this is normal
