Answer 1

Answer:

The correct option is 2) I will subtract 18 days from the length of my shortest cycle.

Explanation:

In order to use the calendar method of birth control, one might know hot to calculate the beginning and end of the fertile period.

The beginning of the fertile period can be calculated by subtracting 18 days from the length of the shortest cycle. This will determine the first unsafe day.

To calculate the end day, subtract 11 from the longest cycle of the person. This will determine the last unsafe day for the month.

The average length of a cycle cannot be used, but the individual's own shortest and longest cycles have to be used for calculation.
