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 from the first day of the woman's last menstrual period (LMP) to the current date.

2. How Does the Calculator Work?

The calculator uses the following simple formula:

Where:

• Current Date — Today's date or any date you want to check
• LMP — First day of the last menstrual period

Explanation: The calculation counts the number of days between two dates and converts them to weeks by dividing by 7.

3. Importance of Gestational Age

Details: Knowing the gestational age helps healthcare providers monitor fetal growth, schedule important tests, and determine the expected due date. It's crucial for proper prenatal care.

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 show how many weeks and days pregnant you are on that date.

5. Frequently Asked Questions (FAQ)

Q1: What if I don't know my LMP?
A: If you're unsure about your LMP, an ultrasound can estimate gestational age based on fetal measurements.

Q2: Is this the same as fetal age?
A: No, fetal age is about 2 weeks less than gestational age since conception typically occurs about 2 weeks after LMP.

Q3: How accurate is this calculation?
A: This is accurate for women with regular 28-day cycles. Variations may occur with irregular cycles.

Q4: What's considered full term?
A: A pregnancy is considered full term between 39 weeks and 40 weeks 6 days.

Q5: Can I use this for IVF pregnancies?
A: For IVF pregnancies, gestational age is typically calculated from the egg retrieval or embryo transfer date plus 14 days.
