Jchic, from what I've read, b6 helps develop follicles, which supports a healthy corpus luteum, which helps extend the luteal phase and boost progesterone levels, which makes implantation more likely. My number 1 priority when I go see the re is to get my progesterone levels checked.
Mrs b, another thing that might help you is to try a high protein, high fiber, lower carb and low glycemic index diet. This would mean cutting down on sugar (fruit is ok, but juice, milk, soda, and sweets would need to be cut down or avoided) and refined, processed grains (cut down on cereal, bread, crackers, etc). Fish, eggs, meat, cheese, greek yogurt, fruit, veggies, beans/legumes, root vegetables, whole grains like oatmeal, quinoa, faro, bulghur, barley, buckwheat are all good. The main focus would be on protein, veg and fruit. The reason for a lower carb, low glycemic index diet is because pcos is associated with higher insulin levels, and carbs, especially refined carbs, trigger high release of insulin as well..
