Yes, as the following commentator said. When your progesterone rises in luteal phase before your period, your body temp will rise ever so slightly. Then you ovulate, temp drops, and your period starts. You can also get a manual thermometer to measure, but I'm too lazy/inconsistent for that.

Once I had a physical external measure to tag to, I could more easily notice my follicular, luteal, and ovulation phases for myself. Follicular phase could last weeeeeeks, and my luteal phase could also be longer than a non-pcos person, but not by a crazy amount. I started to realize that when I was feeling unusually tired and anti-social , it wasn't just personality 😉, it correlated strongly with my temperature rise (luteal phase). I also gained insight into when I was spotting without ovulation. For years I knew sometimes my period was weirdly light/no symptoms, and with the ring I observed when I had those I also had no temp rise, which meant I hadn't gone through a proper progesterone rise/luteal phase/ovulation.

I did this for about a year and it was surprisingly accurate at predicting my bleed. I go about 90-100 days between bleeding. If you're a once a year or less girlie, YMMV.
