We help you come fully into mensuration and your cycles.
As our hormones ebb and flow over the span of 4 weeks, our menstrual cycle biologically has three distinct eras:
When it comes to cycle syncing, your actual period is considered the fourth phase.
Phase | Days (approx.) | What happens |
Menstrual (part of follicular phase) | 1–5 | Estrogen and progesterone are low. The lining of the uterus, called the endometrium, is shed, causing bleeding. |
Follicular | 6–14 | Estrogen and progesterone are on the rise. |
Ovulatory | 15–17 | Estrogen peaks. Testosterone and progesterone rise. |
Luteal | 18–28 | Estrogen and progesterone levels are high. If the egg isn’t fertilized, hormone levels decrease and the menstrual cycle starts again. |
The days listed above are an average time span for each phase. Each person is different.
“Once women have become comfortable tracking their cycle in calendar form, I then teach them to track what they’re feeling each week of their cycle in real time,” Negron says.
“We create a calendar together of phases and plan what projects to prioritize, what workouts, social engagements, self-care, and relationship activities to engage in,” she adds.
