Step 1: Understand Naegele's Rule and its adjustment for cycle length. Naegele's Rule calculates the Estimated Date of Delivery (EDD) by adding 9 months and 7 days to the Last Normal Menstrual Period (LMP), assuming a 28-day menstrual cycle. For cycles longer or shorter than 28 days, an adjustment is made:
Step 2: Calculate EDD for Mrs. Ako.
- LMP: 8th July 2025
- Cycle length: 35 days
First, apply Naegele's Rule for a 28-day cycle: Next, adjust for Mrs. Ako's 35-day cycle: Add the adjustment to the EDD: The EDD for Mrs. Ako is April 22, 2026.
Step 3: Calculate EDD for Mrs. Idris.
- LMP: 8th July 2025
- Cycle length: 26 days
First, apply Naegele's Rule for a 28-day cycle: Next, adjust for Mrs. Idris's 26-day cycle: Subtract the adjustment from the EDD: The EDD for Mrs. Idris is April 13, 2026.
The expected date of delivery for Mrs. Ako is . The expected date of delivery for Mrs. Idris is .
