The baby can be measured as early as 5 or 6 weeks after the motherâs last menstrual period. Measuring the baby using ultrasound is most accurate in early pregnancy. It becomes less accurate later in pregnancy. The best time to estimate gestational age using ultrasound is between the 8th and 18th weeks of pregnancy. The most accurate way to determine gestational age is using the first day of the womanâs last menstrual period and confirming this gestational age with the measurement from an ultrasound exam.
In the low-risk pregnancy group, they estimate it to be between 38 and 39 weeks of gestation. In women 35 years of age and older, they estimate the optimal gestational age right at 39 weeks of gestation.In women with hypertension, they estimate the optimal gestational age to be between 39 weeks and 2 days and 40 weeks and 1 day.Finally, only women with diabetes had an optimal gestational age estimated to be greater than 40 weeks of gestation, between 40 and 41 weeks.Interestingly, this last group is the one that is commonly induced early owing to ongoing increased risk of stillbirth as well as concern for macrosomia.stimate the optimal gestational age of delivery with respect to maternal and neonatal outcomes. Although they are only powered to look at a few of the feasible outcomes, they consistently find that the overall optimal gestational age is less than 40 weeks of gestation.
