Hi Ladies,
I have been charting for the past 6 months. So far it has been uneventful with a my cycle being approx 28 days and a luteal phase of 11 days exactly. It has never wavered until this cycle when I am now on day 15 and still no sign of AF. I temp vaginally and use OPK's so I know when I ovulated. My understanding is that your LP shouldn't change. If it does then its normally only a day or two max.

Has anyone else had this issue? What is going on here?

Thanks!
