Any kind of menopause is irrelevant in a DE cycle, the meds will replace your natural hormones until the (hopeful) pregnancy kicks those hormones into gear. If I remember correctly, the mock cycle included estrogen therapy, to build up the lining, and then progesterone therapy to allow the lining to shed. You'll have your answer tomorrow, but don't worry, the mock cycle is done exactly for this reason... to see how to best make your body respond for the real thing

Lots of good luck.
