Question: I am postmenopausal, and I use bi-est cream and progesterone cream for two weeks. I’d like to know if there is a way to know when my body is in a certain phase, or does it matter? Am I bothering my cycles by arbitrarily starting a “Day 1” at any time?

Larry’s Response:  “Cycles” are defined by the release of an egg, the growth of the lining of the uterus, and the oval of the lining with a “period”. There are no cycles after menopause because no eggs are being released. It makes absolutely no difference what day you set as day ONE. In fact, we usually instruct women just to use the days on the calendar.

Day one is the first of the month. The cyclic use of hormones establishes the cycle for you.
