When to take an ovulation test
Timing is everything
The pre-ovulation part of each person's cycle can vary, but the luteal phase (the part after ovulation) is rather consistent at two weeks. That's why understanding your cycle length is key for tracking ovulation.
If you already know how long your menstrual cycle is, you can use the tool below to determine the best time to start
testing.

If you don't know how long your cycle is, you can use the average cycle length of 28 days as a benchmark—that means you'd start testing on day 12, which is 11 days after the first day of your period.
Do one test per day over a five-day period, or until you detect an LH surge. Each box comes with nine test strips so if needed, you can start testing earlier to make sure you don't miss your fertile window.
When is day 1 of the menstrual cycle?
“Cycle day 1” is the first day of period bleeding. Your cycle length is from this day until the day before your next bleeding begins.
