Hi yes i would go to your doctors,ideally your luteal phase needs to be 12 days.have you tried taking b6 i also had a short luteal phase this has helped and extended mine from 10 days to 13,best of luck.
I think so, I read somewhere on here (today actually) that you might need to take progesterone because the egg might not have time to implant before your lining starts breaking down for your AF. Have a search through the other posts I'm sure it was only put on in the last couple of days.
