[A-2-C]

I find BBT charting the most helpful if you want to find out what is wrong with your cycle, for example, if you have any dysfunction or deficiency, etc.
For example, if your chart looks like the first one then it means corpus luteum deficiency - your body is not producing enough progesterone.
If your chart looks like the second one - this is progesterone AND estrogen deficiency!
Added the third chart - high temperature in the first phase means estrogen deficiency.

And would "ideal" chart look like? Thanks!
