Hey there,
So, you use P cream for 2 weeks on, then 2 weeks off?
I imagine then, that it would be OK to be off for less than 2 weeks? As I mentioned, I'm a period paranoid about NOT using it while still using the E.
I am curious to hear what others are doing also.
My doc also said that it would be OK to use both continuously for a couple or three months at a time, then come off for a "period". That's if I wanted to.

Yes, I do take 2 weeks off, but now I'm having second thoughts ...
Based on symptoms, I think I entered peri when I was 41-42. I didn't start testing hormones until I was 46. My progesterone was below the low end of the normal range for a pre-menopausal woman, but it was probably normal for a perimenopausal woman, especially as far into peri as I was ! But that time I had already missed some periods and my cycles were becoming irregular.
I started supplementing progesterone, cyclically, roughly 2 weeks out of every cycle (it was kind of hard for some cycles because of the irregularity). But after the last dose wore off, I was probably sub-normal again. And this is how I remain, I'm still using the stuff cyclically, 2 weeks on, the rest of the month off.
But prior to peri I'll bet that my progesterone was low for the first half of the cycle but not sub-normal. It was probably in the low-to-mid portion of the normal range, and then after ovulation bumped up higher.
I think I'm interested in restoring a higher overall level of progesterone, which might mean using it every single day, but only using a very small amount the first half of the cycle and using more the second half.
I worked on my Excel spreadsheet tonight. I'm focusing on estradiol but the calculations will work for progesterone as well. I've set it up so that the least amount of estradiol I use on any day is .5mg (which is .25 under the normal EstroGel dose of .75mg), and on certain days I use more. I managed to make a major estradiol peak on day 15 and a minor peak on day 22. I think I'm going to do the same thing with progesterone, use some progesterone every single day, but on some days it's only a very small amount, like 3-5mg, and on the other days when I want to make my peak I'll use more. As soon as I get some solid numbers for you all, I'll post them in this section of the forum. I'll also give the spreadsheet to anyone who wants it. It utilizes half life values, very important to figure in because .5mg/day eventually builds up to a steady state of 2mg after a couple of weeks. Topical estradiol has a half life of 36 hours, the next day you still have some of the estradiol in you from the prior day.
I hope any of this made sense ! I'm getting tired. :-)
