When we become pregnant one of the first burning questions we have is “what is my due date?” Our due date has this magical quality because it symbolises the.

Let me tell you why. Your period length was not taken into account. What can I do? Speak to your midwife or birthing care provider to understand what they based your due date on. Ask them if they took into account the length of your menstrual cycle and your ovulation cycle. Ask them which due date calculation method they used.
So, what IS my due date? Alexia on 7th November at Dave Crowley on 23rd September at Alexia Leachman on 25th September at Babies born even just two weeks early have higher rates of breathing problems, jaundice, feeding problems, temperature regulation issues, and delayed brain development.
Not to mention induction before 39 weeks substantially increases the risk of c-section, which has dangers to the mother and child all its own, so it's not just your baby who can seriously suffer from an unneeded induction and premature birth. The March of Dime's efforts with these hospitals has shown a drastic reduction in premature births and c-sections I hope that their success in North Carolina continues and sets an example and standard for hospitals across the country, so we can eliminate elective inductions.
Your Due Date Is Wrong
After all, every mom wants her baby to be as healthy as possible from the get-go, and after weeks of being pregnant, and decades of life ahead for you and your child, a couple more weeks really is absolutely nothing in the grand scheme of things, but can cause a lifetime of differences. Are you concerned about your "due date"? What do you think of this news from the March of Dimes?

Your Due Date Is Wrong. Other biometric variables, such as additional long bones and the transverse cerebellar diameter, also can play a role.
Date changes for smaller discrepancies 10—14 days are appropriate based on how early in this second-trimester range the ultrasound examination was performed and on clinician assessment of LMP reliability. Because of the risk of redating a small fetus that may be growth restricted, management decisions based on third-trimester ultrasonography alone are especially problematic; therefore, decisions need to be guided by careful consideration of the entire clinical picture and may require close surveillance, including repeat ultrasonography, to ensure appropriate interval growth.
The best available data support adjusting the EDD of a pregnancy if the first ultrasonography in the pregnancy is performed in the third trimester and suggests a discrepancy in gestational dating of more than 21 days.
As soon as data from the LMP, the first accurate ultrasound examination, or both are obtained, the gestational age and the EDD should be determined, discussed with the patient, and documented clearly in the medical record. For the purposes of research and surveillance, the best obstetric estimate, rather than estimates based on the LMP alone, should be used as the measure for gestational age. The American College of Obstetricians and Gynecologists, the American Institute of Ultrasound in Medicine, and the Society for Maternal—Fetal Medicine recognize the advantages of a single dating paradigm being used within and between institutions that provide obstetric care.
Table 1 provides guidelines for estimating the due date based on ultrasonography and the LMP in pregnancy, and provides single-point cutoffs and ranges based on available evidence and expert opinion.

Methods for estimating the due date. American College of Obstetricians and Gynecologists. Women's Health Care Physicians. Recommendations The American College of Obstetricians and Gynecologists, the American Institute of Ultrasound in Medicine, and the Society for Maternal—Fetal Medicine make the following recommendations regarding the method for estimating gestational age and due date: As soon as data from the last menstrual period LMP , the first accurate ultrasound examination, or both are obtained, the gestational age and the EDD should be determined, discussed with the patient, and documented clearly in the medical record.
Introduction An accurately assigned EDD early in prenatal care is among the most important results of evaluation and history taking.

Clinical Considerations in the Second Trimester Using a single ultrasound examination in the second trimester to assist in determining the gestational age enables simultaneous fetal anatomic evaluation. Ultrasonography dating in the second trimester typically is based on regression formulas that incorporate variables such as the biparietal diameter and head circumference measured in transverse section of the head at the level of the thalami and cavum septi pellucidi; the cerebellar hemispheres should not be visible in this scanning plane the femur length measured with full length of the bone perpendicular to the ultrasound beam, excluding the distal femoral epiphysis the abdominal circumference measured in symmetrical, transverse round section at the skin line, with visualization of the vertebrae and in a plane with visualization of the stomach, umbilical vein, and portal sinus 8 Other biometric variables, such as additional long bones and the transverse cerebellar diameter, also can play a role.
Conclusion Accurate dating of pregnancy is important to improve outcomes and is a research and public health imperative.
