Myson - Yeah, they all say B6 to lenghten LP. Another thing I recall reading is that Clomid also lengthens LP. I think the reason is that it stimulates more follicles so more progesterone is released and therefore, LP is longer. But there is always the risk of hyperovulation. You really do need to see that Dr, you need to get the cycles in line! At least it is getting shorter though.
