 Cosmopolitan Magazine Blurb
Saw a blurb about it in Cosmopolitan Magazine ( i think it was.) It was talking about periods and said:
If you don't have your period it could be caused by stress, or if you have irregular or extended absense of periods, than you may have a condition known as Polycsystic Ovary synrom.
(paraphrased, but that's basically it) |
