Signs of a period but WHAT!

I have PCOS and I'm 5 mos out of surgery 6/09/08 and I still haven't had a period naturally.  However this month my body is going the motions of a period (cramps, major headaches, my ovaries pinching me, even a little *****y) BUT NO FLOW.  What the hell is going on and has anyone experienced this?

Any possibility of being pregnant?

If not, it could be taking a few days to start. I do know that occasionally I would have "symptoms" of a period, but no period. that was almost as frustrating as having it!

yes, this has happened to me in the past and just happened to me this week.... I have had PCOS since I was a teenager. I menstruated for the first time in over a year in a half this week. I 100% completely attribute it to the fact that I started drinking spearmint tea. I did some reading that the tea lowers testoserone levels and should help with slowing down the hair growth. Within 5 days of drinking 2 cups a day, I started to get cramps but no flow..... 8 days after drinkning the tea, I menstruated. I recommend trying this out. I got it at a holistic/herbal store. It was 4.50 for 30 bags of tea. Try it out!! Cant hurt, right? I got used to the taste. I add some lemon to it. Good luck!!
