When Do You Ovulate? Is Taking The Test Justified?

With a positive ovulation test result, you now know when your next period will arrive, since ovulation occurs 12–16 days before your period begins.

Here are some ovulation test instructions:

  • You should start taking tests several days before the expected ovulation (with a regular 28-day cycle, it should be on day 11–12).
  • Continue taking the tests until the result is positive.
  • It is better to do tests twice a day (but do not use the first morning urine).
  • Before taking a test, do not drink a lot of water and do not urinate for about 4 hours.
  • Follow the instructions closely (collect urine in a clean container, put the test strip in it for no more than 10 seconds, check the result no later than 10 minutes).
  • If the second line is clear, ovulation will occur in 12–36 hours; a faint line means a negative result for ovulation.
  • To determine fertile days most accurately, you can additionally measure your basal temperature, monitor your cervical mucus during the cycle, and track ovulation by ultrasound.

Ovulation tests: may need to be done twice a day to not miss the peak

The peak of the luteinizing hormone (LH), which is detected in the urine shortly before ovulation, varies in duration and level in different women.

Sometimes, the peak time of LH is short, i.e., it lasts only a couple of hours and, therefore, can be determined only during this period.

To not miss the surge of the hormone, it is better to do tests twice a day at the same time.

If the cycle is regular, then the source data will be approximately the following:

the menstrual cycle length: 28 days

the luteal phase (from ovulation to menstruation, fairly stable, lasts 12–14 days)

the beginning of testing: 3 days before ovulation.

That makes 28 – 14 – 3 = 11. Thus, it is necessary to start taking tests from the 11th day of the cycle (counting from the first day of your menstruation).

Positive ovulation test: what to do next?

A positive test result is indicative of an LH surge, and ovulation should occur in the next 24 to 36 hours.

However, this may not be the case for everyone. Intercourse should take place on the day you receive the positive result and during the 3 days following.

A positive ovulation test represents your best opportunity to get pregnant. If you are unsure of the result, read the booklet that is included with the ovulation kit.

Ovulation test is negative: have you done everything right?

A negative ovulation test means you are not having an LH surge, and ovulation has not occurred. If you are unsure about the results, consult the booklet included with the test.

Reasons for negative results:

  • use of first morning urine
  • the concentration of LH too low to detect
  • testing too early or too late in the menstrual cycle
  • Predicting the LH surge can be tricky, so don't worry if you get another negative ovulation test result. It may have come earlier than planned.

For the most accurate result, doctors suggest testing twice a day, 10 hours or more apart, for a few days prior to ovulation.
