Hi Amanda,
Best of luck with your ferning. I am using one at the moment, but it is a different brand. My friend (the one having twins) fell preggers using it the first time and she had been trying for 11 months. I know of a couple of people who have had good success with it. Just make sure that the saliva is totally dry and don't put on too much or it can take forever the see the dots or ferns.

I fell pregnant the first time I used it but unfortunately that moment of joy didn't last too long. I used it properly this time and I have less than a week left of the TTW, so I can let you know then.

Fingers crossed for you
