Hi Becky. I was experiencing similar problems to you and have been on B6 for two cycles now. While my LP appears to have lengthened slightly I have started getting strange spotting prior to AF's arrival. I went to visit a GP who suggested the the short luteal phases and spotting could be the result of my body not producing enough progesterone since coming off the pill. I have gone for a blood test this week (on CD 14) and will have another one next week (CD21) to monitor my levels.

The GP was explaining to me that quite often B6 will solve or mask the problem but if you find that it doesn't help maybe look at checking out your progesterone levels. I understand if it is a progesterone problem it can easily be treated. I sure hope so!!!
