Baby growth ke hisab se week Dekhe ya last period ke hisab say, because baby growth 6 days Aage chal rahi hai
There are two ways to calculate due date- one by your last menstrural period to get a general idea or baby gestation age which is based on measurement of baby's size in womb. After around 19-20 week ultrasound depending on baby's measurements in womb doctor can tell you a due date more accurately. But there's always a chance of baby being born week before or later than that date.
