Melbell,

Yes, you do have an increased chance of getting preg while b/f'ding if you have PCOS, because b/f'ding makes your body more sensitive to insulin (like taking Metformin). But if you also have high prolactin, then I doubt that that would be the case for you - since b/f'ding would just increase your already high levels. I suppose it is different for everyone, depending on what their probs are. But certainly, if the issue is elevated insulin levels, than b/f'ding helps reduce them.
