Gestational Age Calculator

Calculate how far along your pregnancy is with our Gestational Age Calculator. By entering your Last Menstrual Period (LMP) and cycle length, you can easily determine your gestational age, current trimester, and the weeks pregnant. Stay informed and track the progress of your pregnancy!

Optional Ultrasound Data

What is a Pregnancy Calculator?

A Pregnancy Calculator helps estimate important pregnancy milestones, including your due date, gestational age, and conception date. It uses your Last Menstrual Period (LMP) and optional cycle length to make the calculations. This tool can also track your pregnancy's progress and provide milestone updates throughout the pregnancy.

πŸ“Œ How Does It Work?

  • Enter the first day of your Last Menstrual Period (LMP)
  • Input your cycle length (if different from 28 days)
  • The tool will calculate your gestational age in weeks, along with an estimated due date

The calculator provides a personalized pregnancy timeline, helping you track key milestones from the beginning to the end of your pregnancy.

How is Gestational Age Calculated?

Gestational age is the duration of the pregnancy, measured from the first day of your Last Menstrual Period (LMP). In our Pregnancy Calculator, the gestational age is determined by using your LMP and the cycle length to estimate how many weeks pregnant you are.

πŸ“Œ Understanding Gestational Age

  • Gestational Age: This represents how many weeks have passed since the first day of your LMP.
  • Due Date: Calculated as 280 days (40 weeks) from the first day of your LMP.
  • Conception Date: Estimated based on your cycle length and due date.

Your gestational age will help you track your progress through each trimester of pregnancy and prepare for important events like ultrasounds and prenatal visits.

How Can I Use the Pregnancy Calculator?

To use the Pregnancy Calculator, simply input the first day of your LMP and cycle length (if applicable). The calculator will then provide you with the following information:

πŸ“Œ What You’ll Get

  • Your gestational age (in weeks)
  • Your due date (estimated delivery date)
  • Your conception date (estimated date of conception)
  • Important pregnancy milestones based on your gestational age

By entering these details, the Pregnancy Calculator will help you stay informed about key stages in your pregnancy and provide insight into your pregnancy’s progress.

Can I Track Multiple Pregnancies with the Calculator?

The Pregnancy Calculator is designed to track one pregnancy at a time. However, you can use the tool multiple times to track different pregnancies. Each time, the calculator will provide updated results based on your LMP and cycle length.

πŸ“Œ Using the Calculator for Future Pregnancies

If you are planning more pregnancies, simply enter the new LMP and cycle length to get updated predictions for each pregnancy. You can use this tool for each new pregnancy to estimate the due date, gestational age, and milestones.

How Accurate is the Pregnancy Calculator?

The Pregnancy Calculator provides estimates based on your LMP and cycle length. For individuals with a regular 28-day cycle, the tool is highly accurate. However, if you have an irregular cycle or if you are unsure about your LMP, the accuracy may vary.

πŸ“Œ Improving Accuracy

  • Adjust your cycle length if it's different from 28 days.
  • Use the calculator after receiving an ultrasound scan for more accuracy.

While the tool provides an estimate, it's important to consult with your healthcare provider for more accurate information regarding your pregnancy.

What Milestones Can I Expect During Pregnancy?

The Pregnancy Calculator helps you track the pregnancy milestones you can expect during each trimester. Some key milestones include:

πŸ“Œ Important Pregnancy Milestones

  • Week 6: Heartbeat detectable by ultrasound
  • Week 13: Risk of miscarriage decreases
  • Week 20: Baby starts making noticeable movements
  • Week 24: Premature baby may survive outside the womb
  • Week 28: Baby can breathe
  • Week 40: Baby born

The Pregnancy Calculator provides updates based on your gestational age and helps you stay informed about each significant development during your pregnancy.

Can I Track My Pregnancy Using Ultrasound Results?

Yes! While the Pregnancy Calculator primarily uses the LMP to estimate gestational age, it can also provide more accurate results when you input ultrasound data. An ultrasound scan can help determine the size of the baby and refine the estimated due date and gestational age.

πŸ“Œ Using Ultrasound for More Accuracy

If you have had an ultrasound, inputting the scan date and measurement will help the tool provide a more precise due date and more accurate pregnancy tracking. You can update your data anytime if you get a new ultrasound report.
