This is my second month of using the CBEFM and my first month charting. I purchased the monitor in hopes that it would provide me good direction about my cycle. During the first month I use, I only got low days followed by highs. It never peaked. I then decided to starting charting for the current cycle. I am now on CD24. My chart looks like a series of mountains and temperatures range from 97 to 97.7. It never goes above 97 degrees. The monitor prompted me to POAS on day 10. It was a LOW, followed by 2 more days of LOW. Day 13 through days 24 (today) has been HIGHS.

My cycles were pretty regular throughout my life. Recently, they have been erratic - 42 days, 31 days, 40 days (last three cycles).

Am I not ovulating? Does anyone have any experience with this - no peaks?
