Edit : I want to never mind about answering this then ;)
Anyone have pcos? i think I have it and I'm scared because I heard it causes all sorts of diseases?
Self diagnosis for something like that is not the best idea---see your doctor.
(But) early diagnosis and treatment can help control the symptoms and prevent long-term problems.

Yes I have PCOS, you need an ultrasound scan to diagnosis it. Many women live with PCOS, symptoms differ from person to person. I was put on the contraceptive pill at 15 because my periods were not regular diagnosed with PCOS at 23. My aunt also has it but it didn't stop her having three healthy children.
