The Pregnancy Week Calculator Test estimates the current gestational age in weeks based on the last menstrual period (LMP) date. It provides an accurate assessment of pregnancy progression using standard obstetric calculations.
The calculator uses the pregnancy week calculation formula:
Where:
Explanation: The calculation determines the number of complete weeks that have passed since the first day of the last menstrual period, which is the standard method for estimating gestational age in obstetrics.
Details: Accurate gestational age calculation is crucial for monitoring fetal development, scheduling prenatal tests, determining due dates, and making important clinical decisions throughout pregnancy.
Tips: Enter the current date and the first day of your last menstrual period. The calculator will determine how many complete weeks of pregnancy have passed. Ensure dates are entered in the correct format.
Q1: Why use LMP instead of conception date?
A: LMP is used because it's typically more reliably remembered than conception date and is the standard method in obstetric practice worldwide.
Q2: How accurate is this calculation?
A: This calculation provides a good estimate, but ultrasound measurements in early pregnancy are more accurate for confirming gestational age.
Q3: What if I have irregular periods?
A: For women with irregular cycles, LMP-based calculations may be less accurate. An early ultrasound is recommended for precise dating.
Q4: When should I see a healthcare provider?
A: It's recommended to schedule your first prenatal appointment when you have a positive pregnancy test, typically around 8 weeks gestation.
Q5: Can this calculator predict my due date?
A: Yes, your estimated due date is approximately 40 weeks from your LMP. This calculator helps track progress toward that date.
