Where:
Explanation: This calculation determines gestational age by counting the number of complete weeks that have passed since the first day of the last menstrual period.
Details: Accurate pregnancy dating is essential for monitoring fetal development, scheduling prenatal tests, determining due date, and making important clinical decisions throughout pregnancy.
Tips: Enter the current date and the first day of your last menstrual period (LMP). The calculator will automatically compute the number of complete pregnancy weeks. 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 accurately remembered than conception date, and it's the standard method used by healthcare providers worldwide.
Q2: How Accurate Is This Calculation?
A: This method is the standard clinical approach for estimating gestational age, though ultrasound dating may provide more precise estimates in early pregnancy.
Q3: What If I Don't Know My Exact LMP?
A: If unsure about LMP, consult with a healthcare provider who may recommend an ultrasound for more accurate dating.
Q4: Does This Account For Irregular Cycles?
A: The standard LMP method assumes a 28-day cycle. Women with irregular cycles should consult their healthcare provider for adjusted calculations.
Q5: When Should I Confirm With Ultrasound?
A: Early ultrasound (8-12 weeks) is recommended to confirm dating, especially if LMP is uncertain or cycles are irregular.
