Ovulation and fertilization occur on day 14 of a 28 day menstrual cycle. This is equal to 280 days since the start of the last period, before allowing for cycle length adjustments. A manual pregnancy calculator is based on the original formula observed by Franz Naegele, an obstetrician and German professor in the 19th century. The formula shows that it should work back three months from the day of a woman's last period and add a year. A more accurate pregnancy calculator can be gained by the use of ultrasound scans. The ultrasound is non-invasive and it is used to check the baby's condition. The radiographer measure the size of the growing embryo to predict the likely birth.

A normal pregnancy usually goes to full term that normally lasts from between 38 and 42 weeks. However, you should bear in mind that the average month is for weeks and several days long, not precisely four weeks. For this reason, your health care provider compute how many weeks pregnant you are, as measuring pregnancy by weeks is a far more accurate means to determine length of pregnancy.

Most calculators are based on a gestational period of 40 weeks from the first day of a woman's last menstrual flow. This is estimated by a woman's ovulation and conceives approximately 2 weeks after the first day of your last menstrual flow and carries the baby for 38 weeks.
