Brown spotting when wiping (only had once) ????


I should start my period today or tomorrow. I had intercourse on the day of ovulation. Yesterday I had brown spotting whenever I used the bathroom, when I wiped. Ever since then it hasn’t happened again.. I was wondering if anyone knew what this might be? If I ever do spot it is the day of my period and I spot pink and it picks up this is real unusual for me. So, I’m just curious.
