Conception Date Calculator
Works backward from a known due date or LMP to estimate the most likely date of conception and fertile window. Useful for confirming timelines or understanding paternity timing.
Pregnancy Calorie Calculator
Calculates your total daily calorie needs during pregnancy by combining your basal metabolic rate, activity level, and trimester-specific energy additions. Essential for healthy gestational weight gain.
Baby Size Calculator
Estimates fetal weight and size using gestational age alone or ultrasound measurements (BPD, FL, AC). Used by parents and clinicians to track growth against standard developmental charts.
Pregnancy Cost Calculator
Estimates your total out-of-pocket costs for pregnancy and your baby's first year, covering medical care, delivery, childcare, and gear. Helps families budget before and during pregnancy.

Track contraction duration, frequency, and pain level to estimate labor progress and determine when to head to the hospital. Useful during active labor for first-time and experienced mothers.
Maternity Leave Calculator
Estimate total paid maternity leave income by combining statutory benefit payments with any employer top-up. Use it when planning finances before taking parental leave.
Pregnancy Nutrition Calculator
Estimate daily protein, iron, folate, and calcium requirements during pregnancy based on your weight, trimester, age, and whether you are carrying multiples. Ideal for building a trimester-specific meal plan.
Pregnancy Risk Assessment Calculator
Score pregnancy risk based on maternal age, pre-pregnancy BMI, obstetric history, health conditions, and lifestyle factors. Use it to understand which screening tests may be recommended at your first prenatal visit.
Fertility & Ovulation Calculator
Predict your estimated ovulation date and fertile window using your last period date, average cycle length, and luteal phase. Essential when trying to conceive or track cycle patterns.
Baby Size & Growth Calculator
Estimate your baby's weight at any point in pregnancy by entering gestational age and parental size. Useful at prenatal appointments to compare against ultrasound measurements.
Conception Date Calculator
Work out the likely date of conception from your due date, last menstrual period, or an ultrasound reading. Helpful for confirming paternity timelines or understanding your pregnancy calendar.
Pregnancy Blood Volume Calculator
Estimate how pregnancy expands your blood volume and how that dilution affects your hemoglobin level. Useful for understanding anemia risk and iron needs at each stage of pregnancy.
Pregnancy Risk Assessment Calculator
Score potential risk factors in pregnancy — including maternal age, BMI, medical history, and lifestyle — to get a composite risk indicator. Useful for prompting conversations with your care team.
Pregnancy Sleep & Rest Calculator
Calculate how many hours of sleep you should aim for each night based on your trimester, work demands, sleep quality, and current symptoms. Helps you plan rest during a physically demanding time.
Pregnancy Exercise & Fitness Calculator
Estimates calories burned during pregnancy workouts based on your trimester, fitness level, exercise type, and session duration. Use it to stay active safely throughout each stage of pregnancy.
Due Date Calculator
Calculates your estimated due date from your last menstrual period or conception date, adjusting for cycle length and luteal phase. Ideal for early pregnancy planning and prenatal appointment scheduling.
Fetal Growth Calculator
Estimates fetal weight from ultrasound biometry measurements including abdominal circumference, biparietal diameter, and femur length. Useful for tracking fetal growth between ultrasound appointments.
Ovulation & Fertility Calculator
Predicts your ovulation date and fertile window based on your cycle length and luteal phase, and can project multiple future cycles. Use it when trying to conceive or track your monthly fertility pattern.
Pregnancy Week Calculator
Tells you exactly how many weeks pregnant you are based on your LMP, conception date, or due date, with an adjustment for cycle length. Perfect for confirming gestational age between prenatal visits.
Gestational Diabetes Risk Calculator
Estimate your gestational diabetes risk score using BMI, age, family history, prior GD, and ethnicity. Use this during pregnancy planning or early prenatal care to identify and discuss risk factors with your provider.
Baby Gear Budget Calculator
Estimate your total first-year baby costs by selecting a budget tier, feeding plan, clothing strategy, and childcare months. Ideal for expectant parents building a realistic baby registry or savings plan.
Prenatal Nutrition Calculator
Calculate your recommended daily folate, iron, and combined nutritional score for each stage of pregnancy and breastfeeding. Use it to understand how nutrient needs shift from preconception through postpartum.
Contraction Pattern Calculator
Assess your labor progression stage by entering contraction duration, frequency, pain intensity, and how long contractions have been occurring. Use it to decide whether to stay home, head to the hospital, or call your midwife.
Ovulation Calculator
Find your estimated ovulation date and 6-day fertile window based on your last period, average cycle length, and luteal phase. Use it when trying to conceive or better understand your menstrual cycle timing.
