Explanation: The calculation determines the number of complete weeks that have passed since the first day of the last menstrual period, providing the current gestational age in weeks.
Details: Accurate pregnancy week calculation is essential for monitoring fetal development, scheduling prenatal appointments, determining expected delivery date, and assessing appropriate growth milestones throughout pregnancy.

Q1: Why Use LMP Instead Of Conception Date?
A: LMP is used because it's easier to recall and track, while conception date is often uncertain. Medical professionals worldwide use LMP as the standard starting point for pregnancy dating.
Q2: How Accurate Is LMP-Based Calculation?
A: LMP calculation is generally accurate for women with regular 28-day cycles. For irregular cycles, ultrasound dating may be more precise.
Q3: What If I Don't Remember My Exact LMP?
A: If you're unsure about your LMP, consult with your healthcare provider who may recommend an ultrasound for more accurate dating.
Q4: Does This Calculator Work For IVF Pregnancies?
A: For IVF pregnancies, the calculation should start from the embryo transfer date rather than LMP, as the conception date is precisely known.
Q5: How Does This Relate To Trimester Calculation?
A: Pregnancy is divided into three trimesters: First trimester (weeks 1-13), Second trimester (weeks 14-27), and Third trimester (weeks 28-40+).
