Helen,

I use Maybe Baby too (have just posted another question about it) and last month I got ferns for only a few days, but this month i've had some sort of ferns 7 days in a row!! really don't know if this is right or not though?? also, some months I got no ferns but know I ovulated through CM - therefore perhaps it's not an entirely accurate thing to use?

Sorry I can't be more help!
