The Last Couple Times I Have Used My Sex Toy

The last couple times I have used my sex toy I have had a streak of red blood after I orgasm, but I checked my vagina and there was no blood in there or on the toy, however there has been blood around my clitoris so(the position I'm in causes my clitoris to rub against my sheets) I'm wondering if it's just getting rubbed to much and causing that. Because when I had sex a few days ago I had an orgasm and there was no blood whatsoever. I'm so confused...
