Pregnancy Tracking Calculators

Track every week of your pregnancy with accurate tools. From due dates and gestational age to ultrasound-based timelines and weight gain, these calculators help you monitor your progress and key milestones.

Gestational Age Calculator (AOG)

Gestational age, also known as Age of Gestation (AOG), is the number of weeks a pregnancy has progressed since the first day of the last menstrual period (LMP). This calculator estimates how far along you are in your pregnancy by using your LMP and average cycle length. It’s an essential tool for tracking fetal development and expected due dates.

How Many Weeks Pregnant Are You?

This calculator helps you determine how many weeks pregnant you are based on the date of your last menstrual period (LMP). It also estimates your due date and shows how many weeks and days remain until delivery. Pregnancy typically lasts between 37 and 42 weeks, and knowing your current gestational age helps track important milestones.

Crown Rump Length (CRL)

Crown Rump Length (CRL) is the measurement from the top of the fetus’s head (crown) to the bottom of the buttocks (rump), typically taken between 6 to 13 weeks of pregnancy. This calculator estimates fetal length based on gestational age or helps assess gestational age based on CRL.

Weekly Pregnancy Weight Gain

This calculator estimates the recommended weekly weight gain during pregnancy based on your Body Mass Index (BMI) before pregnancy. It helps monitor healthy weight gain depending on your current pregnancy week, height, and pre-pregnancy weight, supporting optimal health for both mother and baby.

Pregnancy Due Date

This calculator helps expectant mothers determine their baby’s due date — also known as the Estimated Date of Delivery (EDD). By entering the first day of your last menstrual period (LMP), you’ll get an accurate estimate of your 40-week pregnancy timeline.

Find Your Due Date

This calculator helps you find your estimated due date based on the first day of your last menstrual period (LMP). It also provides key pregnancy milestones, including estimated conception date, fertility window, and the end of the first and second trimesters. A simple and reliable way to track your pregnancy from day one.

Ultrasound Gestation Period

This calculator estimates the gestational age of a pregnancy based on ultrasound measurements, such as Crown-Rump Length (CRL) or Biparietal Diameter (BPD). Ultrasound-based dating is especially accurate in early pregnancy and helps track fetal development, estimate due dates, and schedule prenatal care.
