I just posted it on the Trading Post board. I am not sure how many here look at that board...and I would like it to get used by someone trying to conceive. I won't be for many more months...so there's no use in it sitting around...kwim?
You take your first morning saliva from under your tongue and place it on the ovulens. You wait for it to dry, then you look at the results. You are looking for the ferning pattern to show you are ovulating. It's a neat thing!
