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 formula:

Where:

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

Explanation: The calculator counts the number of days between the two dates and converts it to weeks and days.

3. Importance of Gestational Age

Details: Knowing gestational age helps healthcare providers monitor fetal growth, schedule important tests at the right times, and determine the due date. It's also crucial for evaluating if the baby is developing normally.

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 in early pregnancy can help estimate gestational age.

Q2: Is gestational age 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: It's accurate for women with regular 28-day cycles who conceived about 2 weeks after LMP. Variations occur with irregular cycles.

Q4: What's considered full term?
A: A pregnancy is considered full term between 39 weeks 0 days and 40 weeks 6 days.

Q5: When should I see a doctor?
A: Schedule your first prenatal visit as soon as you know you're pregnant, typically around 8 weeks gestational age.
