Fertility

Fertility tracking is more than ovulation windows. Context connects your cycle data, basal temperature, HRV, sleep, and lifestyle factors into a unified picture — helping you and your care team see patterns that isolated apps miss.

Why fertility tracking needs more than one app

The problem
  • Cycle tracking apps give you predictions, but they can't see the full picture — your sleep quality, stress levels, HRV shifts, or how that new supplement is actually affecting things.
  • Basal body temperature in one app, cycle data in another, wearable metrics in a third. The signals that matter most are scattered.

Fertility is deeply personal and multi-factorial. To understand your patterns, you need to connect the hormonal signals with the lifestyle context that shapes them.

Fertility awareness improves when you see how your whole body responds across the cycle.

Playbook

  • Connect your cycle tracker and wearable for automatic data capture (temperature, HRV, sleep stages).
  • Log key markers — OPK results, cervical mucus, symptoms, medications, supplements.
  • Track lifestyle factors — stress, exercise intensity, alcohol, sleep timing, travel.
  • Compare cycles — overlay month-over-month to see if interventions (diet changes, supplements, stress reduction) are shifting your patterns.

What you'll discover

  • How your HRV and resting heart rate shift predictably with cycle phase — and what disrupts that pattern.
  • The lifestyle factors (stress, sleep, exercise) that correlate with cycle regularity and luteal phase length.
  • Whether supplements or protocol changes are actually moving the needle across multiple cycles.
  • Temperature and recovery patterns that help you understand your fertile window with more confidence.

How Context connects your fertility signals

Context layers your cycle data, basal temperature, HRV, sleep, and recovery alongside the daily context that affects reproductive health.

What connects
  • Cycle & hormonal data: period tracking, ovulation markers, basal body temperature, cervical mucus observations, LH test results.
  • Wearable signals: HRV trends (which shift with cycle phase), resting heart rate, skin temperature, sleep stages and quality.
  • Daily context: stress, exercise intensity, nutrition, supplements, medications, travel, sleep schedule changes.

How it works

  • One Timeline with cycle data and biometrics side by side — see how your body responds across each phase.
  • Annotations for symptoms, medications, OPK results, and anything your apps don't capture.
  • Trends to compare cycles and spot shifts in luteal length, temperature patterns, or HRV baselines.
  • AI Insights that surface correlations between your lifestyle and cycle patterns.

Building a fertility awareness project

Understanding your fertility isn't a single month of tracking — it's a 3–6 cycle project where patterns emerge over time.

Set up your fertility project

  • Baseline first: track 2–3 cycles with full data (wearable + cycle app + daily annotations) before changing anything.
  • One variable at a time: introduce a supplement, adjust exercise intensity, or change sleep habits — then watch for 2–3 cycles.
  • Review with Then-vs-Now: compare cycle length, luteal phase, temperature curves, and HRV patterns before and after.
  • Bring data to appointments: share specific, time-bound views with your RE or OB-GYN.

Common experiments

  • Sleep regularity (3 cycles): consistent bedtime and wake time; watch for changes in cycle regularity and luteal length.
  • Stress reduction (2–3 cycles): track stress annotations against HRV and cycle timing.
  • Supplement tracking (3+ cycles): log start date and dosage; compare temperature curves and hormone markers.
  • Exercise adjustment (2–3 cycles): reduce high-intensity training in luteal phase; monitor recovery and cycle response.

Working with your care team

Bring months of connected data to every appointment — not fragments from memory.

Clinician Snapshot
  • A time-bound link with cycle trends, temperature data, HRV patterns, and your annotations.
  • Scoped to fertility-relevant data — share what matters without exposing your full history.
  • Expires automatically (revocable anytime).
Shared Awareness
  • Give your RE or fertility coach ongoing visibility into your tracking for treatment cycles.
  • Share with a partner so you're both informed and aligned.
