A beautiful, supremely talented young friend of our family recently fell victim to a terrible medical mistake. Newly married, she was having some pelvic pain and bleeding, and the doctor who saw her diagnosed a probable ectopic pregnancy — an embryo that develops outside the womb. Concerned that such pregnancies can turn life-threatening, the doctor prescribed the standard treatment: methotrexate, a drug used for chemotherapy and to help induce abortions. When our friend returned to be checked a few days later, the imaging revealed that in fact, the pregnancy had not been ectopic; it was in place, in her uterus. But because she had taken the methotrexate, a known cause of birth defects, her pregnancy was doomed. She soon miscarried. What may have been a perfectly healthy pregnancy had been ended by well-meant medical treatment. I assumed her horrifying case was an exceedingly rare medical fluke — until now. A paper just out in the prestigious New England Journal of Medicine shows that such misdiagnosed pregnancies are part of a pattern — a pattern that needs to be changed.

From that day, weeks of pregnancy is officially counted, and your doc or midwife busts out the red pen and marks your due date on the calendar. Sometimes, however, the due date may be revised.
It can be pretty difficult to determine a due date using the date-of-last-period method for women with irregular cycles — which is why an ultrasound exam is often required to determine gestational age. An early ultrasound, usually done at about 6 to 9 weeks, can give the most accurate due date estimation by measuring the size of the embryo or fetus. However, many pregnancies are confirmed by a Doppler heartbeat monitor, not an ultrasound.
Did you get your very first ultrasound in your second trimester? If so, that could be why your due date shifted. Ultrasounds performed during the first trimester not the second give the most accurate due date predictions, according to a study in the American Journal of Obstetrics and Gynecology.
