Hi Amanda,
I still don't know what luck this cycle will bring with the Ladyfree (like the Maybe Baby) but I could definately see ferns around the time I was meant to be O'ing. They actually look like little ferns when they dry, otherwise they look like dots, kind of like cells. At first I didn't think it was working for me either then I finally saw the ferns.

Make sure you do a test first thing in the morning, before eating or drinking anything. But, having said that I would have a tiny sip of water so everything wasn't all squished together. LOL, aren't we lucky, spitting on things in the morning, checking CM during the day.

I used the OPK's too, but once I went through a whole packet with nothing but faint lines. I gave up on that, otherwise I'd be spending a fortune.

A health nurse who works at the school I am at told me that you usually O about 14 days before your cycle is going to start. Depending on your cycle that should give you a rough idea. The ferns are meant to show up about 3 or 4 days before and stay about 1 or 2 days after O. Try searching the net for the ladyfree biotester as I found a little info about it when I frist started using it.

Best of luck and let me know how the ferning goes. Just make sure you let it dry completely, sometimes I would even leave mine dry for an hour.

Take care and fingers crossed for you
