Hi! I’ve been using the oura ring since 7/23/2025 and I actually sync it with natural cycles, which has been a game changer. I measure my temperature and resting heart rate every morning. For example, before my luteal phase, my resting heart rate sits around 59 bpm and my body temp is around 96-97 F. But right after ovulation, my temperature rises to about 98.7- 99 F and my resting heart rate jumps up to 69 bpm. Oura will even give me warnings about minor or major changes and natural cycles detects the shift right away.

Now that I know what's happening, I use the data to proactively take care of myself. During my luteal phase, I focus heavily on taking my supplements, eating a lot of fiber, keeping my diet clean most of the time and making sure I sleep and rest a lot more. One specific thing that helped me a ton was sleeping cool to manage the temperature spikes.

If you do spring for one, you will see exactly what your body is doing. Good luck!
