When can I do the ovulation test?
You may test at any time of the day, but you should test at approximately the same time each day, according to the makers of First Response test kits. Reduce your liquid intake for two hours before testing.
To find out when to begin testing, determine the length of your normal cycle. The length of your cycle is from the beginning of one period to the beginning of the next. Count the first day of bleeding or spotting as day one.
If your cycle length is irregular, that is, if it varies by more than a few days each month, take the average number of days for the last three months. Use the chart to work out the day you should begin testing. The day you begin testing is listed opposite the number of days in your cycle. For example, looking at the chart, if your period normally begins every 28 days, you should begin testing eleven days from the first day of bleeding of your last period.
| Length of Cycle (Days) | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | 39 | 40 |
| Using the first days of bleeding or spotting as Day 1, count forward the following number of days to begin testing: | 5 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 |
