Pregnancy Due Date Calculator Kaise Kaam Karta Hai?

Pregnancy ka duration average 280 days (40 weeks) hota hai — yaani LMP (last menstrual period) ke pehle din se le kar baby ki expected delivery date tak. Hamara calculator Naegele's Rule use karta hai, jo worldwide standard hai: LMP date mein 7 days add karein, phir 3 months minus karein, aur 1 year add karein. Yeh rule 28-day cycle ke liye perfect hai; agar cycle length alag hai to thora adjust karna parta hai.

Conception date method mein hum assume karte hain ke conception LMP ke 14 days baad hua (ovulation). Is case mein due date = conception date + 266 days. LMP method generally zyada accurate hota hai kyunke zyada tar women apni last period ki date yaad rakhti hain, lekin conception date estimate karna mushkil hai.

Pregnancy Ke 3 Trimesters

Pregnancy ko 3 trimesters mein divide kiya jata hai, har trimester approximately 13-14 weeks ka hota hai:

Week-by-Week Highlights

Week 4-5 — Positive Test!

Aap ki home pregnancy test positive aayega. HCG hormone levels rise ho rahe hain. Baby abhi embryo hai, size ek sesame seed jitna. Folic acid zaroori hai neural tube defects se bachne ke liye.

Week 8 — Heartbeat Detected

First ultrasound mein baby ki heartbeat detect ho jaati hai — 150-170 bpm (adult se 2x tez). Baby ki length 1.6 cm. Fingers aur toes forming hote hain. Major organs develop ho rahe hain.

Week 12 — End of Critical Period

1st trimester almost complete. Baby ki saari major organs ban chuke hain ab sirf grow karenge. Nuchal translucency ultrasound down syndrome screening ke liye hota hai. Miscarriage risk dramatically kam ho jata hai.

Week 18-22 — Anatomy Scan

Yeh sabse important ultrasound hai jisme baby ke saari organs, placenta, amniotic fluid aur growth check hoti hai. Gender usually is time confirm hota hai (agar aap janna chahte hain).

Week 24 — Viability

Is week ke baad agar baby born hua to medical intervention se survive kar sakta hai (NICU mein). Lekin abhi full development nahi hui. Lungs maturing ho rahi hain.

Week 28 — 3rd Trimester Starts

Counter ek qism ki contractions (Braxton Hicks) feel ho sakti hain. Glucose tolerance test diabetes ke liye hota hai. Baby ki eyes open ho jaati hain. Rh-negative mothers ko Anti-D injection lagta hai.

Week 36 — Almost There

Baby descend ho jata hai pelvis mein. Weekly checkups shuru. Group B Strep test hota hai. Bag pack kar lein hospital ke liye.

Week 40 — Due Date!

Sirf 5% babies due date par born hote hain. 37-42 weeks ke beech normal hai. Agar 41 weeks tak labor start nahi hua to doctor induction suggest kar sakti hain.

Important Pregnancy Milestones aur Tests

Nutrition Tips Pregnancy Mein

Pregnancy mein sirf 300 extra calories/day chahiye (2nd aur 3rd trimester mein). Quality matters over quantity. Yeh foods lazmi include karein:

⚠️ Avoid These Foods

  • Raw/undercooked meat, fish, eggs (salmonella, listeria risk)
  • High-mercury fish (swordfish, king mackerel, shark, tilefish)
  • Unpasteurized milk aur cheese (feta, brie, camembert)
  • Raw sprouts (alfalfa, clover)
  • Excess caffeine (200 mg se kam — 1 cup coffee)
  • Alcohol — completely avoid
  • Processed meats (hot dogs, deli meats) unless steaming hot

Frequently Asked Questions

Due date calculator kitna accurate hai?
LMP-based calculator approximately 95% accurate hota hai 28-day cycle ke liye. Lekin sirf 5% babies actually apni due date par born hote hain — 37-42 weeks ke beech koi bhi din normal hai. Irregular cycles, PCOS, ya breastfeeding mothers ke liye ultrasound-based dating 1st trimester mein zyada accurate hota hai.
Agar cycle 35 days ka hai to kya hoga?
Lambe cycle (35+ days) wali mothers ka ovulation late hota hai, is liye un ka actual due date LMP-based estimate se 7-10 din aage ho sakta hai. Hamara calculator cycle length adjust karta hai — 28-day default hai, lekin aap 21-45 days enter kar sakti hain.
Pehle ultrasound kab hona chahiye?
First prenatal visit 6-8 weeks par hona chahiye jis mein viability ultrasound hota hai (heartbeat confirmation). Dating ultrasound 8-12 weeks par best hota hai — yeh due date estimate karne ka sab se accurate method hai. Anatomy scan 18-22 weeks par hota hai.
Preterm labor ke signs kya hain?
37 weeks se pehle agar: regular contractions (har 10 min ya zyada), lower back pain (na clear karne wala), pelvic pressure, water break, vaginal bleeding, ya fluid leak — foran hospital jayein. Preterm labor ko stop kiya ja sakta hai agar jaldi pata chale.
Pregnancy mein kya exercise safe hai?
Normal pregnancy mein 30 min moderate exercise daily recommended hai: walking, swimming, prenatal yoga, kegel exercises. Avoid: contact sports, heavy lifting, hot yoga, scuba diving, aur exercises jismein falling risk ho. High-risk pregnancy (placenta previa, history of miscarriage) mein doctor se consult karein.
