Spuddles,
Sarah is correct that you can have polycystic ovaries but not have the syndrome that can go with it. I think they say as many as 1 in 4 women may have polycystic ovaries and most will never know. i only found out I had them when I was 44 when I started IVF and my sister found out she had them when she was 38. We both have always had regular periods and no other sign of the syndrome.
When I was diagnosed my fertility specialist said to make sure I don't put on any weight as when you have polycystic ovaries weight gain can bring on the full blown syndrome symptoms so the low GI diet might help you out. Also maybe Vitex is not a great idea as it influences your hormone levels so you don't want too many things messing with them
good luck spuddles and I hope you don't have to have another TV u/s again soon but I guess this time you will be prepared. I have had lots and some ultrasonographers are rougher than others. it would have been a shock to have one with no warning.
