Enter your current week, weight, blood pressure, and kick counts to track your pregnancy progress and flag changes for your provider.
It is 11 p.m. in the third trimester and you are lying on your left side, hand on your belly, counting — was that four kicks or five, and was it fewer than yesterday? The appointment that could answer it is two weeks out, and the space between visits is exactly where the worry lives and where the data goes uncollected. This tracker gives you a between-visit log for the numbers that matter most in the second and third trimesters: your current week, pre-pregnancy and current weight, height for BMI context, blood pressure readings, daily kick counts, baby's position, and whether you are carrying one baby or more.
The output is a week-by-week summary that you can bring to each prenatal appointment alongside the clinical measurements your care team takes. Consistent home monitoring means trends are visible before they become urgent, and your provider has context for their measurements rather than reading each data point in isolation.
Weight gain and gestational weight tracking
The tracker asks for both Pre-Pregnancy Weight and Current Weight in pounds. The difference is your gestational weight gain, which the tracker tracks week over week. Recommended weight gain during pregnancy varies based on pre-pregnancy BMI: lower ranges for higher starting BMIs, higher ranges for lower starting BMIs, and specific guidance for multiple pregnancies.
The tracker calculates your current BMI context from the height and weight fields. This context matters because your OB-GYN or midwife uses your starting BMI to set your individual gain target, and knowing where you are relative to that target each week supports the conversation at prenatal visits.
Rapid or sudden weight gain — particularly in the third trimester — can be a signal of fluid retention associated with preeclampsia and is worth flagging to your provider promptly rather than waiting for the next scheduled visit. Track your weight consistently and note any sudden changes.
Blood pressure monitoring between prenatal visits
Blood Pressure (systolic) is tracked in the tool because blood pressure changes during pregnancy are one of the most important variables to monitor, particularly in the third trimester. Preeclampsia — characterized by elevated blood pressure and protein in urine — can develop rapidly, and home monitoring between appointments provides an early warning that clinic-only monitoring cannot.
A home cuff with an arm cuff rather than a wrist cuff gives more reliable readings. Take readings when rested, sitting quietly for five minutes first. Record the systolic (upper) number the tracker asks for. Readings consistently above 140 systolic in someone who was previously normotensive warrant contact with your provider regardless of appointment timing.
The tracker does not calculate whether a reading is concerning — it records it and you share it with your care team. If you have been told you are at risk for preeclampsia, ask your provider how often to monitor and what readings to contact them about.
Kick counts and why they matter in the third trimester
Kick Counts Today Per Hour is the fetal movement monitoring field. From approximately 28 weeks, kick counting is a widely recommended practice for monitoring fetal wellbeing. The general guidance is to count the number of movements in a one-hour period, ideally at the same time each day when the baby is typically active, after a meal.
Typical movement can vary significantly between pregnancies and between fetuses. What matters most is your baseline for your individual baby and any significant decrease from that baseline. A drop in movements from your personal normal is worth calling your provider about rather than waiting for the next appointment.
The tracker records your daily count and builds a running picture of your baby's movement pattern, which is more useful for spotting a change than any single count in isolation.
Baby's position and pregnancy type context
Baby's Position is relevant from approximately 32 to 34 weeks when optimal positioning for delivery begins to matter. The tracker allows you to record what your midwife or OB-GYN told you at your most recent visit. Head down, breech, transverse, or unknown are the options. Position changes are common through 35 to 36 weeks and require no concern before then — but having the record of each visit's position report lets your care team see how position is tracking.
Pregnancy Type — singleton, twins, or triplets — calibrates all the other fields. Multiple pregnancies have different weight gain guidelines, different blood pressure monitoring protocols, and different concerns at each gestational stage. The tracker adjusts its output based on this context. If you are carrying multiples, your care team's specific guidance takes precedence over any general ranges the tracker references.
Between-visit monitoring: what to track and when to call
Most prenatal care schedules involve monthly appointments until 28 to 32 weeks, then more frequent visits. The weeks between appointments are where this tracker provides its value: a consistent record of weight, blood pressure, and fetal movement that you bring to each appointment as supplement to the clinical measurements taken there.
Print the weekly summary before each prenatal visit and attach it to your pregnancy notes folder. If you notice something concerning between visits — a blood pressure reading significantly above your baseline, a day with unusually low kick counts, or rapid weight gain over a few days — contact your provider with the specific data point, not waiting until the next scheduled appointment. Your numbers are the conversation starter your midwife or OB needs.
How to use it
- Enter your Current Week of Pregnancy and select your Pregnancy Type to calibrate the output.
- Fill in Pre-Pregnancy Weight and Current Weight in pounds alongside your Height in inches.
- Record your Blood Pressure systolic reading from a home cuff taken after five minutes of rest.
- Enter Kick Counts Today Per Hour from your regular counting session, ideally after a meal.
- Select Baby's Position based on your most recent midwife or OB-GYN assessment.
- Print the weekly summary to bring to each prenatal visit and flag any significant changes to your care team between appointments.
Who it's for
- Person with gestational hypertension risk monitoring at home — Someone told at 28 weeks they have gestational hypertension risk monitors blood pressure daily and shares weekly summaries with their OB-GYN via portal, enabling their provider to see the daily trend rather than just the clinic reading.
- Person tracking weight gain against individualized targets — A person who started pregnancy at a higher BMI tracks weekly weight gain to stay within their OB-GYN's recommended range, flagging a 5-pound gain in one week for provider assessment.
- Person with a breech baby at 33 weeks — A person whose baby is breech at 33 weeks tracks position at each subsequent midwife visit and notes when the baby turns head-down at 36 weeks, updating the tracker and sharing the record at the next appointment.
- Person managing a twin pregnancy — Someone carrying twins uses the pregnancy type calibration to track twin-appropriate weight gain targets and twice-weekly kick counts as directed by their specialist, building a documented monitoring record across the higher-risk pregnancy.
Key terms
- Gestational weight gain
- Total weight gained during pregnancy, tracked from pre-pregnancy weight. Recommended ranges vary by pre-pregnancy BMI and are set by your care team based on individual factors.
- Preeclampsia
- A pregnancy complication characterized by elevated blood pressure and typically proteinuria, requiring prompt medical management. Blood pressure monitoring between appointments is an early warning approach for at-risk pregnancies.
- Kick counting
- A method of monitoring fetal movement during the third trimester, typically by counting movements in a set period after a meal. Used to track fetal wellbeing between appointments.
- Systolic blood pressure
- The upper number in a blood pressure reading, representing pressure during a heartbeat. The field this tracker records for home blood pressure monitoring.
Frequently asked questions
When should I start tracking kick counts?
Most providers recommend beginning kick counts around 28 weeks. Before that, fetal movement is present but not yet a reliable clinical monitoring tool. At 28 weeks, you will have established a movement baseline for your baby specifically. Discuss the timing and expected count with your care team — guidance varies across practices.
What is a concerning blood pressure reading during pregnancy?
This is a clinical question that your provider is the right source for, as individual risk profiles vary. Generally, a sustained reading of 140/90 or above on two separate occasions in someone who was previously normotensive is a clinical threshold. If you are monitoring at home and seeing readings above your usual baseline, contact your provider with the specific numbers rather than waiting.
Does this tracker replace prenatal appointments?
No. Regular prenatal care including provider assessments, ultrasounds, and lab work are essential components of pregnancy monitoring that cannot be replaced by home tracking. This tracker supplements and supports those appointments by providing data between visits.
How accurate is a home blood pressure cuff?
Upper-arm validated digital monitors are generally accurate when used correctly. Wrist cuffs are less reliable due to positioning sensitivity. Take readings after five minutes of seated rest, with feet flat on the floor and arm at heart level. Consistent technique produces comparable readings. Validate your home readings against clinic measurements at your next visit.
