Conception window

Fertility tracking in PregnancyPal is a daily log of body signals — temperature, cervical mucus, ovulation-test results, and symptoms — paired with a live read-out of your estimated ovulation day, fertile window, current cycle phase, and a fertility score from 0 to 100. Everything shown is an estimate calculated from what you enter; none of it confirms ovulation or diagnoses fertility.

Where the Period feature works mostly from the calendar, the Fertility feature adds the physical signals many people watch when they're paying close attention to their cycle. You log what you observe each day, and the app reflects it back as a phase, a window, and a score so you can see where you are at a glance. It's a companion for noticing your own signals — not a clinical assessment.

What you can do with fertility tracking​

  • See your estimated ovulation day framed as "Today", "In X days", or "X days ago".
  • See your fertile-window date range at a glance.
  • See your current phase — Menstrual, Follicular, Ovulation, or Luteal.
  • See a fertility score from 0 to 100, computed in real time from your data.
  • Log today's data — temperature, cervical mucus, an ovulation-test result, symptoms, and notes.
  • Review recent signals — a temperature trend of your last 5 readings (with average and a comparison to yesterday) and your recent ovulation tests (last 4).

How to log today's data​

  1. Open the Fertility feature (route /fertility).
  2. Tap "Log Today's Data" to open the entry form.
  3. Enter your temperature, choosing Celsius or Fahrenheit.
  4. Pick a cervical-mucus type from the dropdown — Dry, Sticky, Creamy, Watery, or Egg white — and note the fertility-level indicator shown beside it.
  5. Record an ovulation-test result from the dropdown — Positive, Peak, Negative, or Low — if you took one.
  6. Tick any symptoms — breast tenderness, ovulation pain, increased libido, bloating, headache, or mood changes.
  7. Add notes for anything else worth remembering.
  8. Save. Your entry updates the temperature trend, the recent-tests list, and the live read-out at the top.

Examples​

  • Approaching ovulation — Cervical mucus shifts toward Watery then Egg white, an ovulation test reads Peak, and the phase shows Ovulation with the estimated day marked "Today". The fertility score sits high.
  • Reading the temperature trend — After logging temperatures for several days, the last-5 trend shows the running average and how today compares to yesterday, helping you watch for the shift many people look for after ovulation.
  • A quiet luteal day — Mucus is Dry, no test taken, mild symptoms ticked, and the phase reads Luteal with ovulation shown as "X days ago".

Tips​

  • Pick one temperature unit and stay with it. Switching between Celsius and Fahrenheit mid-cycle makes the trend harder to read.
  • Log cervical mucus consistently. The progression from Dry toward Egg white is one of the more informative day-to-day signals, and the fertility-level indicator helps you interpret it.
  • Record ovulation tests as you take them. A Peak or Positive result is most useful in context with the surrounding days.
  • Use symptoms as supporting clues, not proof. Breast tenderness or ovulation pain can support a pattern but don't confirm anything on their own.
  • Watch the window, not a single day. The fertile-window range acknowledges uncertainty better than fixating on the estimated day.

Frequently asked questions​

How is the fertility score calculated?​

The score (0–100) is computed in real time from the data you log — your temperature, cervical mucus, test results, and where you are in the cycle. It's a convenience summary of your own entries, not a clinical measure of fertility.

What do the cervical-mucus options mean?​

The dropdown offers Dry, Sticky, Creamy, Watery, and Egg white, each with a fertility-level indicator. They describe what you observe; the indicator reflects how fertile that type is generally considered. Your own pattern over time is what matters most.

What do the ovulation-test results mean?​

You can log Positive, Peak, Negative, or Low to match the read-out from your own ovulation test kit. PregnancyPal records the result you select — it doesn't read or interpret the physical test for you.

Is the temperature trend the same as a basal body temperature chart?​

It's a simple trend of your last 5 logged temperatures with an average and a yesterday comparison. It can help you watch for shifts, but it's a lightweight view, not a formally charted BBT method with coverline rules.

Is there a separate "trying to conceive" mode to switch on?​

No. There is no dedicated trying-to-conceive toggle. The Fertility feature, together with the Period feature, simply serves anyone tracking their cycle — including people trying to conceive.

Does a high fertility score mean I'll conceive?​

No. A high score reflects that your logged signals point toward a fertile phase; it does not predict or guarantee conception, which depends on many factors beyond what any app tracks.

Can I use this to avoid pregnancy?​

No. The Fertility feature has no contraception logic and must not be used to prevent pregnancy. Speak with your provider about reliable contraception.

What this feature does NOT do​

  • It does not confirm ovulation. The phase, window, and "Today" marker are estimates from your data — they do not detect or prove that ovulation occurred.
  • It does not diagnose fertility or infertility. The fertility score is a summary of your entries, not a clinical evaluation.
  • It contains no contraception logic and must never be used to avoid pregnancy.
  • It does not interpret your physical ovulation test — you log the result you read yourself.
  • It does not account for medications, conditions, or hormonal factors that affect fertility, and it does not alert you to seek care.

Everything here is an estimate, never a diagnosis. PregnancyPal is a tracking companion, not medical advice and not a substitute for professional care. If you're trying to conceive, having difficulty conceiving, or have any concern about your fertility, please consult your healthcare provider — only a qualified clinician can evaluate your fertility.
