Is a progesterone insufficiency evident through charting?
I have been charting for about 1.5 years. When I first started charting my luteal phase hovered around ten days, sometimes dipping to eight to nine days. After some online reading I took Vitamin B6, and my luteal phase soon moved to an average of 13 days, where it has been for several months (occasionally 12, once 15). Could I still have a “hidden” progesterone deficiency that is preventing me from becoming pregnant? Are there other signs of a progesterone deficiency aside from a short luteal phase?
Thank you for your excellent work.
