Temperature tracking

Temperature tracking in PregnancyPal is a quick log for body-temperature readings — useful when you're monitoring a fever, recovering from illness during pregnancy, or tracking basal body temperature in pre-pregnancy mode — with a unit toggle and a trend chart you can hand to your provider.

Pregnancy increases the importance of paying attention to fever. A short illness with a temperature spike is usually fine; sustained or high fever is worth talking to your provider about. PregnancyPal logs make the conversation specific instead of "I think I had a fever yesterday".

What you can do with temperature tracking​

  • Log a reading in seconds: tap the input, type the number, save.
  • Switch units: °C ↔ °F. Existing readings re-render in the chosen unit.
  • Add context: where the reading was taken (oral, ear, forehead, axillary), how you felt, any medication taken.
  • See trends over hours, days, or weeks.
  • Export to PDF filtered by date range.
  • Use in pre-pregnancy mode — if you're charting basal body temperature (BBT) for fertility tracking, the same log works.

How to log a temperature​

  1. Open the log: Dashboard → Vitals tile → Temperature. Or sidebar → Vitals → Temperature.
  2. Enter the value: Numeric input, defaults to your selected unit.
  3. Pick context (optional): Method (oral, ear, forehead, axillary), how you feel.
  4. Add a note: "Kids sick at home", "took acetaminophen at 2 PM", etc.
  5. Save: The entry shows at the top of the log.
  6. Trend: Tap the chart icon to see readings over time.

Examples​

  • Mild fever during pregnancy — At week 18 you spike to 38.2 °C with a cold. You log a reading every 4–6 hours over two days. The chart shows the spike and the gradual return to your normal range. You bring the PDF to your provider's next call to confirm everything was managed appropriately.
  • Pre-pregnancy BBT tracking — In pre-pregnancy mode, you're charting basal body temperature each morning. A small but sustained shift after ovulation is the classic BBT pattern. The trend chart shows it clearly.
  • Recovery from a stomach bug — You log every few hours for two days, see the pattern, and don't have to remember exact numbers when telling your provider what happened.

Tips​

  • Use the same method consistently. Oral, ear, and forehead can vary by 0.3–0.5 °C. Picking one method and sticking to it gives a useful trend.
  • Note medication. Acetaminophen (paracetamol / Tylenol) lowers temperature for ~4–6 hours; readings during that window can mask the underlying fever. Note when you took meds.
  • Don't over-log. Three to five readings during a fever day are more useful than thirty.
  • For BBT tracking, take the reading first thing in the morning before getting out of bed. Consistency is the entire signal.

Frequently asked questions​

What's a fever in pregnancy?​

Generally, an oral temperature at or above 38 °C (100.4 °F) is considered fever, the same threshold as outside pregnancy. Persistent or high fever during pregnancy can warrant a call to your provider — what counts as "persistent" or "high" is a clinical judgment they'll make for your case. PregnancyPal does not flag readings.

Should I be worried about a low-grade fever?​

It depends on context — what's causing it, how long it's lasted, what other symptoms you have. Talk to your provider rather than rely on an app. Fevers in early pregnancy (first trimester) sometimes warrant earlier conversations because of effects on fetal development; your provider's instructions for your stage apply.

Why are forehead readings sometimes lower than oral?​

Different methods sample different sites. Forehead and ear devices are convenient but typically read 0.3–0.5 °C lower than core temperature; oral and rectal are closer to core. PregnancyPal records the method so your provider knows how to interpret.

Does PregnancyPal account for ovulation in BBT tracking?​

In pre-pregnancy mode, the period & fertility feature uses BBT (along with cycle data) for ovulation prediction. Temperature tracking outside of cycle context is just a log.

Can I edit a reading?​

Yes. Tap any entry to edit value, time, method, or note. Delete via swipe (mobile) or menu (web).

Does the export PDF include the trend chart?​

Yes — the PDF has the date range, a line chart of all readings, and a tabular log with timestamps, methods, and notes.

What this feature does NOT do​

  • Diagnose fever, infection, or illness. Temperature is one data point; diagnosis requires clinical context.
  • Predict whether a fever is dangerous. Severity depends on cause, duration, gestational age, and other symptoms — all clinical judgments.
  • Replace a thermometer. PregnancyPal logs the number you enter; it does not measure temperature.
  • Send alerts. No reading triggers an automatic notification or message to your provider.

If you have a high fever, persistent fever, or fever with other symptoms during pregnancy, call your provider. Don't wait on the app to tell you something is wrong — it won't.
