Hi poppet I'm afraid I'm no expert on this but I have read that LP is not always 14 days, some are as short as under a week and others are 16 days or so. For those who do have a short LP there are some vitamins (or similar) you can take to lengthen it though.

Are you temping? I think that's a good indicator of when things are happening. I haven't started temping yet but will probably do so next cycle if I don't get my wish this one!!!

Good luck, I hope someone can shed some more light for you.
