CBE fertility monitor off on peak dates?

Question

The CBE fertility monitor gave me a peak on CD18 and CD19. I'm 99% sure that I ovulated on CD17 though. I had spotting, lots of CM and my temps were low all that day although not until a few hours after I had taken my temp that morning. I think that I ovulated that night and I got my peak the following morning. In the past when I have done OPK's, I've gotten a postive on the actual day that I ovulated and the day after. Maybe it did that again with the monitor and I ovulated late on CD17 so for some reason it didn't pick up my peak until the next day? All the monitor did for me was confirm that I do ovulate late, but I KNOW it is not CD19 and probably not CD18. *sigh* My temp did jump up a bit on CD18 (97.9) and then this morning it's up real high (98.2) so I would think that shows that I did in fact already ovulate. It is usually 97.7 on average.
I would share my FF chart, but am not sure how to do it.

Here is a link to my chart:

I was off almost an hour on my temp this morning (earlier) so not sure how much that affects it.

If you are using FertilityFriend, log into your chart. Over on the left point to the "Sharing" button and then click "Home Page Setup" At the top you will see "Your Charting Home Page Web Address": and it will be something like this (this like is to my chart) http://www.fertilityfriend.com/home/321c...
Copy and Paste YOUR link to send to anyone you want to have your chart. I'll check back tomorrow and if you could add additonal details with your chart link that would be great!

Looking at your chart, I'm saying you probably O'd on CD18.
