Oh, the joy of PCOS (sense the sarcasm)! It's completely normal for a woman with PCOS to have a period here and there, but not consecutively. Since you did have sex, I would recommend taking a pregnancy test just for peace of mind to ensure the condom didn't break. If you start noticing any pain in your ovarian area, be sure to get into to see your Gynecologist to make sure you don't have too many cysts built up and blocking any eggs from releasing.
