hi have pcos. i am married 10 years now. still no kids and have been trying for a long time now. have been on provera as well as a few cycles of clomid. for the past few months my period has been quite regular. it use to be very irregular so for the jan, feb, and march of this year it was normal coming 25 or 26th of every month however for april i have experienced something weard. i noticed a week before my period was due i had a pinkish spot on my underwear thinking ok my period must have started. however nothing came after that no period. i did however have prementrual cramps. so now its may and i have started experiencing pms again from 25th of this month for 4 days now but nothing. should i be worried. could something seriosly be wrong
