Frequently Asked Questions
Q: 38 weeks pe labor kab bhi start ho sakti hai?
A: Haan! 38 weeks pe baby fully developed hai aur labor anytime start ho sakti hai. But many babies wait until 39-41 weeks. Only 5% babies come on their due date. Be ready but also be patient - baby will come when ready.
Q: Water break hone pe kya karna chahiye?
A: Note the time it happens and the color of fluid (should be clear or slightly pink). Put on a pad. Call your doctor or go to hospital. If fluid is green, yellow, or smells bad, go immediately - could indicate baby passed meconium.
Q: Nesting bahut ho rahi hai - labor jaldi hogi kya?
A: Nesting is common in final weeks but doesn’t predict exact labor timing. It’s your body preparing, but labor could still be days or weeks away. Don’t exhaust yourself - you need energy for labor and early days with baby.
Q: Baby ke nails itne bade hain - scratch kar legi kya?
A: Yes, newborn nails can be sharp! Baby may even scratch face in womb. After birth, you can file nails gently or use baby mittens. Many hospitals trim nails before discharge. Never bite baby’s nails (infection risk).
Q: Itni insomnia ho rahi hai - kaise soyun?
A: Insomnia affects 2/3 of women in late pregnancy. Try: sleep schedule, comfortable pillows, cool room, relaxation before bed, avoid screens, empty bladder before lying down. If severely affecting daily function, talk to doctor.
