Explanation
Choice B is correct. February 12th would be the estimated date of delivery. Subtract three months from May 5th and add seven days equating to February 12th.
Choice A is incorrect. Start with May 5th (LMP). Subtract three months, which brings us to February 5th. This does not follow Nägele’s rule.
Choice C is incorrect. Start with May 5th (LMP). Subtract three months, which brings us to February 5th. Adding seven days to February 5th would lead to February 12th. Therefore, January 28th is not a correct calculation.
Choice D is incorrect. April 12th is not a correct calculation based on Nägele’s rule. It does not follow the process of subtracting three months and adding seven days to the LMP.

Additional Info
✓ Nägele’s rule involves subtracting three months from the date the last menstrual period began, adding seven days, and then correcting the year, if appropriate.
✓ Nägele’s rule is less accurate when the woman’s menstrual cycle is very irregular.
✓ Ultrasound measurements taken early in pregnancy (before 20 weeks of gestation) can more accurately determine the gestational age.
