Clearblue Easy Fertility Monitor? Anyone used this?

[BabyGirl2013]

I'm thinking about purchasing the Clearblue Easy fertility monitor, but wanted to see if anyone has used this?

Does it rely on previous cycles to predict OV or can I use it from my first TTC cycle? It will also be my first month off birth control.

I just want to get the earliest prediction of OV possible since DH travels BUT he could rearrange his schedule if we know my fertile days a few days in advance. The description says it can predict up to 5 days in advance of peak fertility, but I wasn't sure if that was once it had tracked your cycle for a few months or if it relied solely on your hormones on any given day.

Thanks!

I think you do have to use it a month in advance, someone correct me if I'm wrong??

If my DH was away a lot, I do think it could be beneficial (because you can DTD any day of high fertility and still be in with a chance) but otherwise I'm not sure they're worth the expense.

I got pg the first month I used it -- yes, it tracks your cycles, but from what I understand it also measures hormones differently than regular OPKs. It told me I o'd earlier that month than I normally did (or THOUGHT I normally did), which was lucky because we only had a chance to DTD early in my cycle that month.
