I am 30 years old and diagnosed with Polycystic Ovary Syndrome when 21. Never on pills but had cycles every three months. I started taking apple cider vinegar last year for cold and sore throat. I realised that my periods had come fairly regularly compared to my history. So I started taking it regularly. After adjusting the qty and dosage for a few months I found that taking a half tbsp Apple Cider Vinegar with half tbsp honey in warm water just before bed suited me the best. I am very glad that I have had 10 cycles in 10 months. My suggestion is natural route does work. We need to be patient and find what works as a few herbs or supplements may not work for all. It's a great feeling to finally be normal with regular cycle.
