Bleeding after masturbation

Mayne

So I masturbated this morning (clitoral only) and afterwards there has been some bleeding. I just wanted to know if this was normal?

My period finished around 5 days ago.

I did have a kidney infection a few months ago which formed from a UTI. But i think I had a vaginal infection first because I did a lot of running in hot weather. Would the bleeding be from this?
