This is my second cycle charting using Fertility Friend. I have long cycles (45-55 days). Last cycle, my temps were very erratic, but I got crosshairs on CD 34 and my period started 15 days later. This cycle my temps seem much more "normal," but I got a huge drop this morning, CD 25. I thought it was odd, but went back to sleep (I temp at 5:45 every morning). I took my temperature when I woke up again around 8, and it was almost a degree higher! My question is, which temp would you use? Normally, I would discard it, but I think I'm in my fertile window because I've been seeing EWCM and I want to be as accurate as possible. I'm also unsure about my original low temp at 5:45 because I did not sleep well and was cold when I woke up. I slept well from 5:45-8:00. Here's a pic of my chart, when I temped again at 8 it was 97.52
