Don't know whether you are on sequi or conti from the description, but do know all the other are not to do with horses. Have a look on the tabs at the top for the different preparations for pre meno and post meno, then do your own research on the recipes by using the search on this site.
I started Jan this year on Elletste conbi ( post meno) - didn't suit me always round. After three months I changed to Femoston Conti and so far, after1 month's, I'm doing better but it's still early days. Generally, the ladies on here say you have to give each recipe 3 montnbs or more. The difference in the combos is the type of progesterone. Some suit us better than others. The other difference of is the amount of estrogen - all a case of trial and error.
Good luck.
