Orgasm make my period come sooner?

I’ve never had intercourse, but I was recently fingered for the first time. About 5 days after being fingered, I noticed some brown bloody discharge. It is around my ovulation time, but ovulation bleeding doesn’t typically happen for me. I was about halfway through my cycle when I got fingered, and I’ve used tampons before so I don’t think my Hymen tore (“cherry popped”). It’s not time for my period, and I don’t have an infection. What could this be? Should I be concerned?
