Spotting vs period

Jo

We have been having unprotected sex and this month I got my “period” two days early however it’s was just very light spotting and went on for about 9 days. I still am very bloated and swollen boobs and feel like I am basically pmsing but am not? Has anyone else had this before? I do have pcos as well but I excessive 5-6days a week and try to stay healthy so I’m not sure if it’s that?
