Estimated date of birth on the basis of the date of ovulation
This method applies only to women who know exactly when they ovulate.In general conception occurs in the days of ovulation.Therefore, this period is counted 280 days and the resulting date is considered the date of delivery.For example, you are planning a pregnancy - made rapid tests or ultrasound to determine ovulation, therefore, know exactly the day of its occurrence.So, using this method will get accurate results.
