Due Date — Sabse Important Date For 9 Months
Pregnancy confirm hone ke baad sabse pehla sawaal — "delivery kab hogi?" Doctor se miloge toh woh bhi calculate karenge — lekin khud jaanna chahte ho toh due date calculator bahut kaam aata hai.
Important samajho — due date ek estimate hai. Sirf 5% babies exactly due date pe aate hain. Most deliveries 37-42 weeks mein hoti hain — yeh "term" range hai.
Due Date Calculate Karne Ka Tarika
Naegele's Rule (Most Common):
Due Date = LMP (Last Menstrual Period) + 280 days (40 weeks)
Ya: LMP Date + 9 months + 7 daysExample: LMP: 1 January 2026
- + 9 months = 1 October 2026
- + 7 days = 8 October 2026 (Estimated Due Date)
Pregnancy Timeline — Week by Week (Quick Overview)
- 1-12 weeks (1st Trimester): Organ formation, morning sickness common
- 13-26 weeks (2nd Trimester): Baby movements start, anomaly scan at 18-20 weeks
- 27-40 weeks (3rd Trimester): Baby growth, delivery preparation
