I am 39 week pregnant my labour pain not start

A. Not a problem sometimes labour can trigger by the time of 40 weeks and 41 weeks also taken ultrasound with the doctor if this everything is good you can still wait then you should wait for that much of a time or if you want then you can get a sweep stretch done or you can have castor oil that would help you sleeping in the labour and another 48 hours both the procedures are same so talk to your doctor about it
