Bleeding after masterbating

Cristal

Hi! i have been trying to figure this our for a while but every time I masturbate constantly with my vibrator( no fingers) . I tend to start spotting and sometimes get things like this it’s been a week after my period. So it can be that but it’s constant. I’ve tried searching up what it could be but not answers also I’ve gone to the ObGym to see if it could be something internal but my scan came out normal and ideas?
