There are many benefits to knowing the estimated due date. It can assist in tracking your baby’s growth and development throughout the pregnancy. Having the estimated due date will assist your obstetrician in tracking the results of the teat he/she may perform. If you are aware of the date when you conceived your baby, you may have already estimated the due date of your baby. During the first appointment with your obstetrician he/she will ask you questions in order to attempt to estimate an accurate due date.
The due date of your baby is normally 10 months or 280 days from the first day of your last period. This rule of thumb is not accurate for all women because not all women have regular or 28 day cycles. It is likely that your obstetrician will order an ultrasound in order to accurately predict the due date of your baby.
