First determine the length of your menstrual cycle - which is the number of days from the first day of your period
(menstrual bleeding) to the last day before your next period starts. -
Think back over the last few months to decide what your usual cycle length has been. -
Circle your usual cycle length on the WHEN TO START CHART. -
Then look down to the number directly below. Count ahead that number of days from the first day of your last period. -
This will be the day you begin testing.

Count ahead this many days STARTING WITH THE FIRST DAY of your LAST period. |
Note: If you are unsure about your cycle length, you may want to use your shortest cycle length when reading the chart. If you do this, you may need to test for more than 5 days.
Example: "My usual cycle length is 28 days. My last period started on the third. The "When to Start Chart" shows that I will count ahead 11 days beginning with the third. When I count 11 days ahead on the calendar, I find that I will collect and test my urine starting on the 13th.
