Hey, Im on Yaz and I have been on it since February. I lost my pack, and things have been hectic with my husband being sick, so I went without for four months. No period, as a matter of fact I was put on birth control at the age 15 to have a period, I belive the hormones in it is what I need, but everytime I go to the doctor I ask if she can do a test to see if something is wrong with me but she never does. But for some people with PCOS I was wondering if I have that? If you can give me some info on it I would be thrilled and maybe talk to my dr in my next visit, also, I went off from my story. I have 2 days left with the white pills and i havent gotten my period yet...should I be concern? If you have any tips they would highly be appreciative..you can reach me at
