I was masturbating the other day with something small. I finished and saw I was bleeding but it stopped soon after. I am on birth control I have had sex before and it wasn't time for my period, not even close. Is this normal?

Normal? No. Something to worry about? No way for us to tell.

It sounds like you were a bit too rough, weren't lubricated enough, or cut yourself somehow. Chances are that it will heal without incident. Wait a few weeks before masturbating again, to give it time to heal. If you're concerned, see your doctor. We can only guess on this site, so my post is by no means a diagnosis.

Good luck. :)

What was the "something" small you were using, it is possible it is not the right thing to use, it can be many things, from a cut to being too rough,
