Squirting Blood?!

I’ve squirted before during clitoral orgasms and there were no problems but today I squirted from fingering for the first time and at first there wasn’t any blood but after I finished I looked down and there was a puddle of blood and cum there. I’m on the pill and am not due for a few more days for my period. I showered after and there was no blood, nor is there any blood continuing to come out now. Is it possible that it was too rough? What is this?
