When you finally know for sure that you are pregnant, your next question will undoubtedly be "When will my baby be born?" Delivery usually occurs 280 days after the first day of the last menstrual period. An easier way to calculate the delivery date, or due date, is to add nine months and seven days to the first day of your last normal menstrual period. Most women don't give birth on the exact date, but 80 percent give birth within ten days of this date -- either ten days before or ten days after.
As your pregnancy progresses, your doctor can double-check your due date with the timing of certain events. For example, the baby's heart is usually heard at 10 to 12 weeks. The level at which the top of the uterus can be palpated (felt) by the doctor is another clue; at 20 to 22 weeks, for example, it is usually at the umbilicus (navel). If your physician performs an ultrasound examination, the technician can measure the baby's head and compare the result with standard tables to estimate gestational age.
Discovering that you are pregnant is a thrilling moment. The next nine months will be filled with excitement both for you and your family.
