Stop taking the PM, take a hormonal stabalizer like Maca or Rhidiola (sp?) to get your hormones back in order. Don't start back up on PM until you know your new cycle, so once you get your period mark it down on which days. And then wait another month until you get your period again and make sure it's the same time as your last period or wait another month until you body's hormones are back to normal. PM messed up my cycle badly as well, before my cycle was at the beginning of the month, now it's at the end.

Just a note on Maca and Rhodiola. Maca gave me horrible headaches and Rhodiola (by Thorne) made me very irritable instead of energetic... progesterone cream (Progest is what I have) can help regulate the cycle when used from day 15 or so until menstruation os due).
