During pregnancy, the only surprise we really enjoy is finding out if we're having a girl or a boy (and that's only if we don't prefer the delivery room shocker). We're a nervous bunch, moms-to-be ... we want to know what's going on in the womb and we want to know when our due date.
Until now, due dates were determined by information we gave our OB/GYNs during our first visit (date of menstrual period, etc.), but that's about to change. The American College of Obstetrics and Gynecologists (ACOG) has joined with American Institute of Ultrasound in Medicine and the Society for Maternal-Fetal Medicine to release new guidelines on how they'll estimate a woman's due date. They're now recommending first trimester ultrasounds.
And that means less surprises -- in a good way! -- for expectant moms.
