Morning. I'm debating what 'gadget' to help me through the next cycle, and hopefully help me achieve a BFP :) This cycle I've used Clearblue Advanced OPKs, I'm not sure if they have detected ovulation a few days earlier than what it happened, but none the less it gave me the heads up to be getting on with DTD. I've been looking at the Clearblue Fertility Monitor as have heard quite a few success stories with it. I wondered if it was worth switching to this. I don't suppose anyone knows the difference between the two, why one is better than the other, and so on? Thanks.
