Ngla: It does help with producing more EWCM, you just take it according the directions on the bottle, mine says two to three times a day so I just take two during the day and swallow them with a glass of water they are just like vitamins.
As for how long until you see a change well I can not remember hun I think I noticed a change that very cycle of when I first took them but it is so long ago so don't qoute me on that.
I don't take it every month but the months I do there is definatly more CM.
Hope this helps and your right just take it from cd1 to O then stop.
