Why Use a Pregnancy Due Date Calculator?
Knowing your estimated due date allows you to:
Plan prenatal visits and ultrasounds more effectively
Track pregnancy milestones like heartbeat, first movements, etc.
Prepare emotionally and physically for delivery
Monitor the baby’s development and maternal health
It’s also helpful for doctors and midwives during early prenatal care.
How Is the Due Date Calculated?
The most common method is Naegle’s Rule:
Due Date = First day of LMP + 280 days (40 weeks)
This calculation assumes a regular 28-day cycle and ovulation around Day 14. Your actual due date may vary, if you’re cycles are not regular. In such cases, ultrasound dating in early pregnancy may offer more accuracy.
Pregnancy Milestones by Week
Week 4-5: Pregnancy confirmed by test
Week 6-9: First heartbeat via ultrasound
Week 12: End of first trimester
Week 20: Anatomy scan and gender detection
Week 28: Start of third trimester
Week 37-40: Full term and expected delivery
When Should You See a Doctor?
As soon as you confirm pregnancy, it’s best to schedule your first prenatal appointment. Early care can help keep both mother and baby healthy and happy. Based on the results of an ultrasound scan, the doctor may alter the date of due.
