It is probably nothing more than a skin tag that you have unknowingly scratched at and become bloody. I've had skin tags that have done that on other parts of my body. And I have a number of tags "down there" too.
However, you're going to have to go to a skin doc for confirmation. And the doc will biopsy it, because they biopsy everything, but the doc will know straight up if it is anything, and will tell you, with the caution that the biopsy will clear it.
Go as soon as you can so you can calm yourself.
Best of luck.
