Why Use a Pregnancy Calculator?
A Pregnancy Calculator is a simple tool that helps you estimate your due date and track your pregnancy week by week. By entering the first day of your last menstrual period (LMP) and your cycle length, you can see when your baby is expected to arrive and what’s happening at each stage of pregnancy.
What is a Pregnancy Calculator?
A pregnancy calculator uses Naegele’s Rule (LMP + 280 days) to estimate your expected due date (EDD). Adjustments are made for cycle length to provide a more accurate timeline. This tool is widely used by doctors and parents-to-be to follow the pregnancy journey.
- EDD = First Day of Last Period + 280 days (40 weeks)
- Adjustment: Add/subtract days if your cycle is longer or shorter than 28 days
Pregnancy Stages (Trimester Breakdown)
| Trimester | Weeks | What Happens |
|---|---|---|
| First Trimester | 1 – 12 | Baby’s organs begin forming, heartbeat starts, early symptoms appear |
| Second Trimester | 13 – 27 | Baby grows rapidly, movements felt, anatomy scan done |
| Third Trimester | 28 – 40 | Baby gains weight, organs mature, labor preparation begins |
Why Track Pregnancy Week by Week?
Tracking your pregnancy week by week helps you understand baby’s development, prepare for doctor visits, and adjust lifestyle choices. From early heartbeat detection to final labor signs, each week brings exciting changes.

FAQs
1. How accurate is a pregnancy calculator?
A pregnancy calculator gives an estimated due date, not the exact delivery date. Most babies are born between 37 and 42 weeks.
2. Can I use this if I don’t know my LMP?
Yes, but the estimate will be less precise. An ultrasound scan can provide a more accurate dating.
3. Why is cycle length important?
The average cycle is 28 days. Longer or shorter cycles affect ovulation and due date calculation. Entering your exact cycle length improves accuracy.
