WTF Is Going On in My Body?

Most male bodies run on a 24-hour hormone cycle like the sun.

You? You’re the moon—shifting over 28ish days.

Your cycle is guided by four key hormones and typically spans around 28ish days. For people with hormonal imbalances, irregular periods, or in transition phases like perimenopause, the durations and energy patterns can shift.

The Guide Every Body With a Cycle Deserves ✿

Learn what your hormones are doing each week so you can finally feel aligned, not confused.

  • Your menstrual phase is your inner winter the "slow-your-roll phase", where estrogen and progesterone hit their lowest and your body calls for rest, renewal, and real nourishment.

  • Your follicular phase is your inner spring the "ultimate reset" phase, where rising estrogen and FSH boost your energy, creativity, and optimism as your body gears up for ovulation.

  • Your ovulatory phase is your inner summer the "time to pop off" phase, where estrogen and LH peak, giving you extra glow, magnetism, and your highest fertility window.

  • Your luteal phase is your inner autumn the "permission to take space" phase, where progesterone rises, energy shifts inward, and your body asks for slowing down and deeper care.

  • Your average cycle is more of a range than a rule. Most people land between 24 and 35 days, so if you’re somewhere in there, you’re cycling exactly as you should.
