Q1: Why use 30.44 days per month?
A: 30.44 represents the average days per month (365.25 days per year divided by 12 months), providing a more accurate calculation than using fixed 30-day months.
Q2: How accurate is this calculation?
A: This provides a good estimate for tracking pregnancy months. For precise medical dating, healthcare providers may use ultrasound measurements and other clinical assessments.
Q3: What is the typical pregnancy duration?
A: Full-term pregnancy is typically 40 weeks or approximately 9 months. The calculation helps track progress toward this timeline.
Q4: Can I use this for IVF pregnancies?
A: For IVF pregnancies, the calculation should start from the embryo transfer date rather than LMP. Consult with your healthcare provider for accurate dating.
Q5: Why does the calculator show both months and weeks?
A: Pregnancy is commonly tracked in both months and weeks. Medical professionals often use weeks for more precise tracking of fetal development milestones.
