Hi Doll Estrogen drops after ovulation and stays relatively low through the remainder of the cycle. Progesterone is high during most of the luteal phase but then drops a few days before your period. I'm not sure about progesterone cream lengthening the cycle. It makes sense that it might be able to do that if taken at the very end of the luteal phase by someone with normal hormone levels. I definitely need to look into it. It seems possible to me that PC might either lengthen or shorten the cycle in the case of progesterone deficiency, depending on what's going on with the other hormones at the same time.

Now you have me thinking that it might be best to take take it for a few days at the very beginning of the luteal phase. In that case, I wouldn't be able to use BBT charting to tell me when to take it. I would just have to take it every single month, with occasional breaks. In that case the BBT charts will be for monitoring purposes only. There's also still a chance that they'll suggest that I have a hormone imbalance, so I guess it's still worthwhile to do BBT.

If I take it for such a short time, the purpose would be to resensitize the estrogen receptors, not to grow directly from the PC itself. Actually it's not clear that this isn't also what's happening in people with PCOS, who generally have very high estrogen and androgens in combination with low progesterone. However that wouldn't apply to Ginie because she did not have PCOS, and she had low levels of progesterone and estrogen. This is all very confusing

I might ask Isabelle for her opinion on the best time to take PC.
