NaeNae,
Is that the Saliva test?
They dont really work as well as they are supposed to. (I used it when I had a very positive OPK and it didnt even fern.)
You have to not eat or drink for 3 hours before using it. And you do it every day. It looked pretty cool at the time, but its a little bit of a hastle IMHO!

What OPK's have you tried? I brought two sorts of OPKs. I brought from ebay... One lot through impregnancy and the other ones through lullaby conceptions.

The ones off ebay from impregnancy are so sensitive and i got my very first positive this cycle. I highly recommend these type. And they are heaps cheaper. They come in a pack of 40 opks and 10 hpts.

Do you know if your definately ovulating? Have you had cd21/7dpo progesterone tests done? How long have you been ttc? xx good luck hth x
