Yes, I've had this before. It honestly might be your "cycle" for the month. I've had regular periods for a year and then that happened, I didn't get it for a few months, and then it went back to "normal" for me. PCOS is a nasty, fickle disease and it probably just is the way your body responded this month. I used to get bogged down when it would Halle , especially if nothing changed.. But the sooner I realized that PCOS will do what it wants... I felt better, I guess? Lol
