Like mentioned earlier, a due date calculator only gives an estimation; so missing your due date by a few days in both directions is usually not a cause for concern. Generally, the doctor would only be worried about premature birth or overdue babies.
Prematurity occurs when the baby is born before the start of their 37th week in the womb. Since preterm birth is a risk factor for various health problems, the doctor would monitor you and your baby closely. It would also help if you watch out for the signs of labor so you could seek medical help as soon as possible.
Late-term pregnancy, when the baby’s still in the womb at 41 weeks to 41 weeks and 6 days, as well as post-term pregnancy, when you still haven’t given birth by 42nd week and beyond, also place you and your baby at risk. If your baby is overdue, your healthcare provider may consider inducing the labor.
Your due date is the estimated date of your baby’s arrival. You can learn how to calculate the due date using an app of due date calculator. But please remember that the result is just an estimation.
Missing your due date by a few days is generally nothing to worry about. But if your little one comes prematurely or is overdue, the doctor would want to attend to you and your baby more closely.
