Cat,
I only know what works for me. Since I hadn't had a period that I could remember, I just started it and let my body take a natural course to get it regulated. It is 7 days off and 21 days on. I started my first period in less then a couple of days using it. I needed it so badly it effected me very Quickly. I then started on a regular 28 day cycle. This is the fourth period I'v had! It seems great to be right. My periods however have been very painful. What I have read it takes 4-6 months to possibly get over this also. A month into this I started TSP wol. These two together are a wonderful combination. But you have to remember you are healing. I feel the best I have felt since I can remember. And if you look in my journal you will see my weight is starting to listen as well. Hope this helps! Let me know how it goes!!
