How to plan your work around your menstrual cycle

Start with your four phases

A cycle is not "period" and "not period". It moves through four phases — menstrual, follicular, ovulatory and luteal — and each carries a different quality of energy, focus and capacity. In a 2022 study of 1,867 women, 86.9% reported a moderate to severe impact of their cycle on mood at work, and 89.3% on energy levels.^[1] The fluctuation is real. Planning around it starts with knowing where you are.

If the phases are new to you, our plain-English tour of the four cycle phases is the place to begin.

What tends to work in each phase

This is a general guide — your personal patterns matter more than averages, and no phase makes you less capable. Different, not less.

Menstrual phase: protect and reflect

Day 1 is the first day of your period. Oestrogen and progesterone are at their lowest, and energy often follows. Where you can, keep this stretch lighter: reflection, reviewing, slower-paced work. Push big launches and dense social commitments elsewhere if you have the choice.

Follicular phase: start and build

The stretch after your period ends. As oestrogen rises, many women notice energy returning, focus sharpening and motivation building. It suits new projects, creative work, learning and the complex tasks you have been putting off.

Ovulatory phase: connect and present

The roughly six-day window around the release of an egg. Oestrogen peaks and testosterone rises, and many women find this the most naturally social and communicative time of their cycle. If you can choose when the big presentation, the interview or the difficult conversation happens, this is a good candidate.

Luteal phase: finish and refine

The roughly two weeks before your next period. Attention often narrows and turns inward — useful for editing, administration, detail work and wrapping things up. As the phase closes, energy tapers; protecting your evenings is not a weakness, it is good scheduling.

How far ahead can you plan?

Further than you might think. Because phases repeat, an estimate of your next few cycles lets you look weeks and months ahead: spotting that a conference lands in your late luteal phase, or that a free week lines up with your follicular energy. The estimates will not be perfect — cycles shift with stress, travel and illness — but even an approximate map beats no map.

Make it visible where you already plan

The reason most cycle-aware planning fails is that the information lives in a separate app you have to remember to open. Nadi takes the opposite approach: it adds your four estimated phases to the Google or Apple calendar you already use, so your phases sit alongside your meetings while you plan your week. No new app to download.

An honest note on estimates

Nadi calculates your phases from the averages you provide — it counts back from your next predicted period rather than guessing a midpoint. You can read exactly how we calculate your phases, including what the method can and cannot tell you. Nadi is a planning tool, not an ovulation predictor or contraceptive method, and no calendar-based method can pinpoint the exact day of ovulation.
