Bleeding during ovulation week

Last month (December 16th) I started my period. It lasted 7 days I was off for two days. Me and my partner did the deed. I started bleeding the next morning like a regular period for another 5 days. Then it stopped.

Skip to January. I started on the 16th again. Had a 5 day period. 5 days after me and my partner did the deed. I started spotting brownish/ to light pink for a few days and I think it’s over with now.

Has anyone experienced this?
