Her perspective was that as it helps increase progesterone, and lengthen the
luteal phase, then it is a positive. Now keep in mind, she is an OB, not an RE. I am going to ask her more about it at my next appointment, as that has me curious. I knew about the thinning of the lining, but want to clarify the "older women" issue.
I don't know if a longer period is a good thing in terms of the lining, but it would make sense to me if that was the case. Good luck on next O!!!!
