very worried! Bleeding after masturbating!

So I masturbated about 2 hours ago with a dildo. The dildo wasn't too big at all but had a little bit of a ridge - but it didn't hurt AT AL as I was doing it actually it felt really good.
When I finished I looked and there was a little smudge of pinkish blood on the dildo. 
Now 2 hours later I went to pee, and when j wiped there was blood on the toilet paper :( 
I am not due for my period for maybe 3 weeks so it can't be that. And I'm not pregnant as I haven't had sex. 
Did I scratch myself?? Should I be scared?? I'm so worried! Please don't tell me to go to the doctor as I am too ashamed. :( 
Ps I'm not a virgin
