Weight tracking

Weight tracking in PregnancyPal is a calm log of your weight throughout pregnancy — chart over time, optional target range from your provider, kg or lb units, and a PDF export. Designed to show the trend without the noise of daily fluctuation and without the anxiety of a "you're 0.3 kg over!" alert.

Weight gain in pregnancy is normal, expected, and varies a lot between people. Different pre-pregnancy BMIs lead to different recommended ranges, and the actual trajectory has natural ups and downs (water weight, hydration, food timing). PregnancyPal logs your weight, shows the trend, and stays out of your way. It does not lecture, judge, or color-code your readings against anyone else's average.

What you can do with weight tracking​

  • Log a reading in 5 seconds: numeric input, time defaults to now.
  • Switch units: kg ↔ lb (Settings → Units).
  • See a smoothed trend chart that filters out daily noise so the actual trajectory is visible.
  • Set a target range from your provider (optional) — shown as a band on the chart, not a "you're outside!" alert.
  • Add notes for context — late dinner the night before, illness, etc.
  • Export to PDF for appointments.

How to log a weight reading​

  1. Open weight tracking: Dashboard → Vitals tile → Weight. Or sidebar → Vitals → Weight.
  2. Enter the value: Numeric input in your selected unit.
  3. Optional note: Anything that explains the reading ("after big meal", "first thing morning").
  4. Save: The entry appears at the top of the log.
  5. View the trend: The chart smooths daily noise — most people use a once-weekly cadence so the chart shows the gain trajectory without daily wobble.
  6. Export when needed: PDF for an appointment.

Examples​

  • Weekly cadence — Every Sunday morning before breakfast you weigh in and log. The trend chart shows steady weekly gain in line with your provider's expected range.
  • Provider-set target band — Your provider gave you a range of 11–16 kg total gain for your pre-pregnancy BMI. You enter that range as a target. The chart shows the band; your trajectory tracks gently within it.
  • Off-schedule day — You weighed in two days late, after a big restaurant meal. The chart shows a small bump, then resumes the trend the following week. No alert, no judgment — just data.

Tips​

  • Pick one consistent time. Morning, before eating, after using the bathroom is the most reliable.
  • Don't weigh daily. Daily weights swing 0.5–1 kg from food and water alone. Weekly readings show the trend with less anxiety.
  • Use the same scale. Different scales read differently. The trend on one scale beats accuracy across many.
  • Don't focus on the number. What matters is gentle, steady progress in the range your provider supports. Wobble is normal.
  • If you've struggled with disordered eating, talk to your provider before tracking weight. The honest answer for some people is to skip this feature entirely — that's a valid choice, and PregnancyPal works fine without it.

Frequently asked questions​

How much weight should I gain?​

Recommended ranges depend on pre-pregnancy BMI. The Institute of Medicine (2009 update) suggests roughly: 11.5–16 kg (25–35 lb) for normal-BMI singleton pregnancies, more for underweight, less for overweight or obese. Twin pregnancies have higher ranges. Your provider's target overrides any general guidance — every person's situation is different.

Why doesn't PregnancyPal warn me if I'm gaining too fast or too slow?​

Because weight in pregnancy fluctuates and individual targets vary. Generic alerts cause unnecessary anxiety without adding clinical value. Your provider sees your trajectory at appointments and is the right person to flag concerns.

Does PregnancyPal account for my pre-pregnancy weight?​

If you entered it during onboarding, yes — the chart can show absolute weight or change-since-pre-pregnancy. Otherwise the chart shows absolute values only.

Can I switch units mid-pregnancy?​

Yes. Settings → Units → Weight → kg or lb. Past readings re-render in the new unit; nothing is lost.

What if I haven't been weighing regularly and want to start?​

Just log today's weight. The chart starts where you start. Earlier gaps are visible as gaps; the trend appears once you have a few weekly readings.

Can I delete a reading I don't want recorded?​

Yes — swipe left (mobile) or use the menu (web).

Does the export PDF include the chart?​

Yes — header (your week range), trend chart, target band if set, and the full table.

My weight is fluctuating a lot. Should I be worried?​

Day-to-day swings of 0.5–1 kg are normal from food and water. A meaningful change is the weekly trend. If your weekly trend is going up or down faster than your provider's target range, talk to them — but a single noisy reading isn't the signal.

What this feature does NOT do​

  • Diagnose under- or over-gain, or any condition. Diagnosis is clinical, not algorithmic.
  • Compare your weight to other people's pregnancies. What looks "high" or "low" is personal and depends on your starting point and your provider's targets.
  • Suggest diet changes based on weight. PregnancyPal's meal planner is independent — it doesn't react to weight readings.
  • Send weight data anywhere. Your readings stay in your account. Sharing means exporting.
  • Lecture you. No "you should walk more!" or "you've gained too much this week!" — those are conversations for your provider, not an app.

If your weight is concerning to you, the conversation belongs with your provider, who can place it in the context of your overall pregnancy. PregnancyPal logs; your care team interprets.
