I started spotting like i was on my last day of my period on my expected ovulation. does this mean my cycle starts all over or i'm expected my period?

None: your cervix may be bruised from sexual intercourse in the last 1 to 2 days. have you used any devices for masturbation that may have injured your vagina or cervix since yesterday? If the spotting happens more often or there is more bleeding, an appointment with gynecologist would be helpful. if you've had regular menstrual cycles, it is unlikely to have an earlier than usual period.
