Common questions about pregnancy calculation and tracking
Our calculator uses Naegele's rule, which is the standard method used by healthcare providers. It's accurate within about 2 weeks for most pregnancies. Only about 5% of babies are born exactly on their due date, with most being born within 2 weeks before or after. Your healthcare provider may adjust your due date based on ultrasound measurements.
LMP (Last Menstrual Period) is the most common method used by doctors because it's easier to remember. It assumes a 28-day cycle with ovulation on day 14. Conception date calculation is more precise if you know exactly when conception occurred, but this is often uncertain. Both methods are reliable for estimating your due date.
Yes! Our baby size comparisons are based on medical data for fetal development. The fruit and vegetable comparisons help visualize your baby's growth in a fun, relatable way. Keep in mind that every baby develops at their own pace, and these are average measurements. Your healthcare provider will monitor your baby's specific growth through ultrasounds.
Recommended weight gain depends on your pre-pregnancy BMI. Generally, women with normal BMI should gain 11.5-16 kg (25-35 lbs), underweight women should gain more, and overweight women should gain less. Our calculator provides general guidelines, but always consult your healthcare provider for personalized recommendations based on your specific situation.
Our calculator provides a general timeline for prenatal appointments, but your healthcare provider will create a personalized schedule. Typically, appointments are monthly until 28 weeks, then every 2 weeks until 36 weeks, then weekly until delivery. High-risk pregnancies may require more frequent visits.
