CBEFM for long/irregular cycles?

I’ve been using the CBEFM since June. My cycles are 30-34 days in length. I’m not sure if this is a bad thing or not but I stop testing after I get my peak (because I here ya, they are STUPID expensive). The monitor gives 2 peaks followed by a high, I don’t feel the need to continue to test afterwards. When I begin the next cycle, I just turn on the monitor and set it for day 1. I find it’s helpful in determining fertile days, way easier then OPKs, I thought they all looked positive unless I used an expensive digital. I’m not pregnant yet but liking the monitor. By the way I purchased it off of kijiji for $70 so that softened the blow. Good luck to you!

I just bought one (yes crazy expensive) but haven’t started using it because I am waiting for CD 1. Do you by chance have PCOS? It did say it doesn’t work with that. Also, it really only is accurate with cycles less than 40 days. I range from 30-36 with some occasional over 40 so we will see if it works for me.  I think the reason is they make you open 10 strips at once, if you have longer cycles you have to open a 2nd set of 10 strips=20 per cycle. If you go through the first 20 strips and no high days then it may not allow you to go on further.. Thats just my understanding from reading it, I could be wrong. If you want more info I can pull it out of my box again and look up the exact explanation for you.

I had PCOS and Long Cycles (as you know!) and the CBEFM was kind of a waste for me. I spent a fortune on sticks, and the only time it worked for me was pinpointing O from Clomid, the two times that happened.

I didn’t have any luck with it.  I like temping much better, but then I have PCOS and OPK’s and the like just don’t work for me.
