Definitely talk to your doctor before you start anything, but I know that a lot of ladies have had success with B6. I took it for most of this cycle and my LP went from 10 days to 12 days (and counting)...AF still isn't here yet, she'll probably show her ugly face tomorrow. GL!
I don't have any advice on the cream or B6 - definitely check with your doctor before starting anything (unless he/she was the one to point you in that direction). I have no idea if it's related at all, but I've started with the pomegranate/pom juice the past couple of cycles, and the days I've spotted has decreased. I haven't found anything online to substantiate the pom juice links to fertility, but it's a nice coincidence, just the same.
