How short is your luteal phase? Mine has only ever been about 10 days and it hasn't affected conception in our case.

On the O pain, have you ever had an ovarian cyst? It sounds similar to what a friend of mine described who suffered from very bad cysts on one side. Is the pain every month or intermittent? Is it just on one side? She had it so bad she did end up losing an ovary, but she says it was such a dodgey one she was better off without it. She conceived both of her boys after that with no difficulty.
