Clear blue advanced fertility monitor

Lucinda
I've just bought the Clearblue Advanced Fertility Monitor off a friend & I'm just waiting for it to be delivered! Was just wondering if anyone had used it before & whether you had much success with it?!
I'm very excited but anxious at the same time as me & my husband have been ttc since our first born son, Eric was sadly stillborn this May. We desperately want our rainbow! ?
