What Cycle Phase Am I In? How to Find Out

To find your cycle phase, count from day 1 (the first day of your period): days 1 to 5 are menstrual, days 6 to 13 follicular, days 14 to 16 ovulatory, and days 17 to 28 luteal. If your cycle is irregular, your symptoms, energy, and cervical mucus give strong clues about which phase you are in.

Find your phase by cycle day

Day 1 is the first day of full flow. For an average 28-day cycle:

  • Days 1 to 5: menstrual phase, your period.
  • Days 6 to 13: follicular phase, energy rising.
  • Days 14 to 16: ovulatory phase, your peak.
  • Days 17 to 28: luteal phase, winding down toward PMS.

Find your phase by how you feel

If your cycle is irregular or you lose track, your body signals your phase.

  • Bleeding: menstrual phase.
  • Rising energy, clearer skin, better mood: follicular phase.
  • Peak confidence, high libido, egg-white cervical mucus: ovulatory phase.
  • Bloating, cravings, low mood, breakouts: luteal phase.

How do I know what phase of my cycle I am in?

Count from the first day of your period: days 1 to 5 menstrual, 6 to 13 follicular, 14 to 16 ovulatory, 17 to 28 luteal. Your symptoms and energy confirm the phase, especially if your cycle is irregular.
