I started reading this and thought, "OH! That's just like me!" and then realized I was being quoted! Hahahahaha! Fuzzy Brain!
Yes, as soon as you get AF. That's what I did.
One month as an experiment I even waited until day 10 and my lining was low, I think 6? And then I drank it for 4 days and got up to 11. Some of that is also natural build up, absolutely, but the techs doing the scans were impressed.
I can't say it will help everyone but I am a strong believer!
Also, just to be clear, I had no endo issues at all, i don't know the effect on that, please ask a dr!
Hugs and thick-good lining to all!
