1. What is Gestational Age?

Gestational age is the common term used during pregnancy to describe how far along the pregnancy is. It is measured in weeks and days from the first day of the woman's last menstrual period (LMP).

2. How Does the Calculator Work?

The calculator uses the standard pregnancy wheel calculation:

Where:

• LMP Date — First day of last menstrual period
• Current Date — Today's date or any specified date
• Gestational Age — Result in weeks and days

Explanation: The calculation follows the standard obstetric practice of counting pregnancy from the first day of the last menstrual period, which is approximately 2 weeks before conception actually occurs.

3. Importance of Gestational Age Calculation

Details: Accurate gestational age calculation is crucial for monitoring fetal development, scheduling prenatal tests, determining estimated due date, and making important clinical decisions throughout pregnancy.

4. Using the Calculator

Tips: Enter the first day of your last menstrual period and the current date (or any date you want to check). The calculator will provide gestational age in weeks and days along with the estimated due date.

5. Frequently Asked Questions (FAQ)

Q1: Why is gestational age calculated from LMP rather than conception?
A: LMP is used because it's a definite date that most women can recall, while the exact conception date is often unknown.

Q2: How accurate is this calculation?
A: This method provides a standard estimate. For more precise dating, early ultrasound measurements are recommended.

Q3: What if I have irregular periods?
A: For women with irregular cycles, LMP-based calculation may be less accurate. Ultrasound dating is preferred in these cases.

Q4: When should I see a doctor for confirmation?
A: Always consult with a healthcare provider for official pregnancy dating and prenatal care guidance.

Q5: Can this calculator be used for IVF pregnancies?
A: For IVF pregnancies, gestational age is typically calculated from the embryo transfer date plus 14 days.
