What is an Ovulation Predictor?

Ovulation causes a rise in basal body temperature, providing a natural way to predict it without using any techniques. However, an ovulation predictor kit can detect the level of the hormone LH (Luteinizing Hormone) in urine, which increases just before ovulation. This LH surge signals that ovulation is likely to occur within the next 36 hours.

Using an ovulation prediction kit not only helps you identify the start of ovulation but also informs you about your most fertile days. To recognize your most fertile days accurately, start using the kit before you expect to be fertile to avoid missing out on them. One method to estimate fertile days involves calculating ovulation based on your menstrual cycle. Ovulation typically occurs 14 days before your next menstrual cycle begins. Subtracting 14 days from the duration of your shortest menstrual cycle gives you the earliest possible day of ovulation. Subtracting 3 more days from this figure ensures that the LH surge is not missed.

For example, if your shortest cycle is 24 days, start using the ovulation predictor kit on the seventh day of your menstrual cycle. Remember to count the day you start bleeding as the first day of your cycle. Since each cycle may vary, you may need to continue testing until you get a positive result. This method, known as the urine LH stick method, involves using brands like Clearblue or First Response, which are available online or at local pharmacies.

Interpreting the results can be tricky, as the LH level in urine may not always be sufficient to produce a clear positive line indicating ovulation. Therefore, obtaining a simple positive or negative result may be challenging initially, but continued testing will eventually yield a positive result as LH levels rise with ovulation onset.
