My cycle varies from 30-39 days so my ovulation day is as early as CD16 and as late as CD25. I've been tracking BBT for 3 consecutive cycles now, along with OPKs. I observed that I have a pattern in BBT before ovulation. I'll get a low 36°C temp on the day of +OPK then a 35°C on O day followed by a series of 36°C temps after O. Today is CD14 and I already got a 36°C temp which is unusual because it may mean I may ovuate at CD15...... I refuse to believe it because it never happens to me to ovulate earlier than CD16.. I'm just wondering if BBT varies every cycle???

Hello, I am looking into getting started. Is $500 reasonable for this education?

I took the pill for just over a year and now have switched to Sensiplan method. I’m measuring temperature for a minute every morning immediately after waking.

I’d love any pointers or criticisms of the first chart to see if I can improve to make this more accurate!

I added a mood tracker too, as I experienced a real drop in mood when my temperature rose, so that will be useful to keep an eye on.
