How to calculate the delivery date
1. The calculation method of the expected date of delivery is: the number of months of the last menstruation is increased by 9 or decreased by 3, and the date is increased by 7. If the lunar calendar is used, the calculation method of the month is the same, and the date is changed to15;
2. Other methods: The fetal movement of primipara occurred in 18 gestational weeks. Because of experience, multipara can feel fetal movement two weeks earlier than primipara, that is, on the weekend of 16, so the calculation formula is: the expected date of delivery of primipara is 22 weeks after the date of fetal movement, and the expected date of delivery of multipara is 24 weeks after the date of fetal movement.
