I am 29 years old, and my fiance and i are trying to conceive our second child. I have very irregular periods and when i do have them they are very long and painful or very short and hardly any blood. I haven't had my period for th month of september and i am still witout it now. i have been cramping but it doesn't result in a menstral cycle. 3 weeks ago i took a blood test which came back negative. My doctor told me that i could have something called Polycystic Ovarian Syndrome AKA PCOS. has anyone ever heard of this?
