PROBABLE DATE OF DELIVERY

Оглавление

And now our expectant mother desires to know when to expect the little stranger. From countless observations of childbirth under all conditions and in many countries, the pregnant period is found to cover about thirty-nine weeks, or two hundred and seventy-three days. There are a number of ways or methods of computing this time. Many physicians count back three months and add seven days to the first day of the last menstruation. For instance, if the last menstruation were December 2 to 6, then, to find the probable day of delivery, we count back three months to September 2, and then add seven days. This gives us September 9, as the probable date of delivery. The real date of delivery may come any time within the week of which this calculated date is the center.

As a rule, ten days to two weeks preceding the day of delivery, the uterus "settles" down into the pelvis, the waist line becomes more comfortable, and the breathing is much easier.

On the accompanying page, may be found a table for computing the probable day of labor, prepared in accordance with the plan just described.
