Just ordered mine not long ago and although it does cost $$$ I don't think its going to be too bad.
Given that you have normal cycles you should only have to use 10 sticks per month and 30 come in a box. As for purchasing the sticks, they are 36.99 on Amazon and usually run about 25 bucks or so on ebay...
Bekr24:I have mixed feelings about it. I have pretty regular 27-29 day cycles and the monitor just confirms what I see on the OPKs ('peak' on monitor usually happens same day or the morning following my first positive OPK). It makes me feel better that I have 2 tools agreeing on when I *should* be ovulating but knowing what I do now, I probably wouldn't spend the money on it - especially considering if you need to buy an extra package of test sticks they are about $50.
This is a good point that I failed to mention - it was really great for me when I was having cycles that were in the 50+ days -- it really helped. Now that my RE has informed me of my thyroid issues and I've been on medicine for a month, my cycles do seem to be returning to "normal"
You can order a three months supply of test sticks on Amazon for about $30.
I was thankful I used it the first cycle as I o'd really really late (I was sick). i would have thought something was wrong, but I did get a peak and temps confirmed I O'd.
This month, I got no peak readings, but I did get a positive OPK, so I'm not sure what to think yet.
I just started using one a couple of cycles ago. I am borrowing a friends, so I didn't have the high initial outlay. The sticks aren't bad (they cost less than digital OPKs).
The two things I like most about the CBEFM are (1) you use FMU; and (2) I get peaks. I never got a positive OPK.
I still chart to confirm O, but it is nice to have a heads up. My cycles are fairly consistent (26-30 days). My O day has been between CD 15 and 18.
