Delivery date rule: Unveiling the secrets to seamless shipping
– A typical pregnancy lasts on average 280 days, or 40 weeks.
– The first day of the last normal menstrual period is considered day 1 of pregnancy.
– An estimated due date can be calculated using Naegele’s Rule.
– Naegele’s Rule involves three steps:
1. Determine the first day of the last menstrual period.
2. Count back 3 calendar months from that date.
3. Add 1 year and 7 days to that date.
– Naegele’s Rule is based on a normal 28-day menstrual cycle, so adjustments may be needed for longer or shorter menstrual cycles.
– There is also a chart available to estimate the delivery date using steps 1 and 2.
