CB Advanced Fertility Monitor?

[crabette]

...has anyone got one of these Clearblue Advanced Fertility Monitors? Are they worth the money?

I don't know if they are but I have bought one second hand on eBay in the last week to try. On the plus side they seem to resell well so if it doesn't work for me I can try selling it on. I'm giving it a go because the cheap OPKs don't seem to work well for me so thought I'd try something else to see if I can work out when I'm ovulating (or about to) more precisely.

Yeah the cheap OPK's aren't working great for me either. I've ordered some of the clearblue OPK's, just not sure if I need the machine as well! Never thought of looking on eBay, will have a look, ta.

I'm not sure how much difference the machine makes, other than it explains for us I guess. I probably need that lol. But yes, it's definitely worth a look on there, I managed to buy a second hand one with a set of the CB strips to use, so I'm really hoping it can pick up my ovulation better than the cheap ones.
