OK, basically when I started using my microscope I had partial ferns up til I got a full fern and now I have nothing.
I still use it everyday, as it states.

"Even though you think you know your ovulation pattern, you have to assume that when it gives you a full fern you are about to ovulate" Well thats what I was told anyways.

So in other words, you can still get full ferns or even partial ferns after ovulation.

Are you temping?
