Real-World Examples

Example 1: First Pregnancy Planning

Situation: Maria's last menstrual period was January 15, 2025, with a regular 28-day cycle. She wants to know her due date and current pregnancy week.
Using the calculator: LMP: Jan 15, 2025, Due date: October 22, 2025 (280 days later), Current status: depends on calculation date
Result interpretation: Based on a January 15 LMP, Maria's estimated due date is October 22, 2025, with pregnancy progressing through standard weekly milestones.
Next steps: Maria should schedule her first prenatal appointment around 8-10 weeks, begin taking prenatal vitamins, and track important milestones throughout pregnancy.

Frequently Asked Questions

How accurate are pregnancy due date calculations?

Due date calculations are estimates based on average 280-day pregnancies. Only about 5% of babies are born on their exact due date, with most births occurring within 2 weeks before or after. Ultrasound dating in early pregnancy is most accurate.

What if I don't remember my last menstrual period?

If you can't remember your LMP or have irregular cycles, your healthcare provider can use ultrasound measurements to estimate your due date. Early pregnancy ultrasounds (6-10 weeks) are most accurate for dating.

Do pregnancy calculators work for IVF pregnancies?

For IVF pregnancies, use the embryo transfer date rather than LMP for more accurate calculations. Your fertility clinic will provide specific dating based on embryo age and transfer date.
