You have to use a BBT thermometer, not a regular one as those aren’t sensitive enough. Track at the exact same time each morning as soon as you wake up. You cannot sit up, take a drink, go to the bathroom, any movement or activity affects temp. Just wake up and pop the thermometer in your mouth right away. Then enter it in Glow. Start on CD 1 (first day of period) if possible. You can start later, just know that you aren’t capturing the beginning of the cycle.

To be able to track accurately and to fully understand the patterns and to troubleshoot any weirdness, you should really read Taking Charge of Your Fertility by Toni Weschler. I did this and got a BFP in just two cycles (unfortunately, it didn’t stick, but my tracking did work). If you read this book you will be leaps and bounds ahead of the game. I see a ton of women on here trying for many months or years who haven’t really learned all the details of charting accurately and it breaks my heart so I am trying to tell this to anyone who’ll listen. If you want the very best shot, read the book. It’s available at most libraries or can be ordered new or used on Amazon.
