Fertility window and ovulation predictor

The fertility window is the time period in which fertilization of an egg by sperm can occur. Typically, that window spans only 6 days in a menstrual cycle: the day of ovulation and the 5 days prior to that. How to increase chances of getting pregnant?

First, determine your cycle and time of ovulation.

Second, have sex more regularly during your fertility window.

Third, eat foods that increase fertility and take fertility supplements.

Fourth, take good, approved supplements designed for boosting fertility.

The easiest way to determine the fertility window is the calendar method. First, measure the time between menstrual periods. For example, the first day of your period is day 1, then wait until the next period starts, and this is the last day of your menstrual cycle. The length of the menstrual cycle is between 24 to 35 days. (if you measure less than 24 or more than 35 days (more than two consecutive cycles), please consult your doctor.

Another method for finding your optimal fertility window, to determine the day of ovulation, is to subtract 14 days from the length of your cycle. That is, if you’re menstrual cycle is 30 days, subtracting 14 puts ovulation at day 16 from the first sign of blood. Then, subtract 5 more days from the result (if day 16 is your day of ovulation, 16 minus 5 is day 11). Those 6 days—the day of ovulation and the 5 preceding days—comprise your fertility window.

However, if the duration of your menstrual cycle changes between cycles, or if your menstrual cycle is not regular, a more accurate method is required. It’s important to note that about 3% of women suffer from luteal phase (the latter portion of the menstrual cycle) dysfunction and require medical intervention.

Accurate prediction of day of ovulation is required in all of the aforementioned cases, and includes:

  • Measurement of basal body temperature between periods. Basal body temperature (BBT) decreases just before an egg is released in ovulation. It then increases sharply 24 hours after ovulation. For 2 to 3 months, measure and record your temperature every morning before getting out of bed. The day the temperature decreases is the day of ovulation. Record how many days from the first day of bleeding this occurs: your fertility window spans 2 days earlier to 2 days later within each cycle.

  • Cervical mucus is stretchy, slippery, thin, and clear during the 5 to 6 days before, and during the day of ovulation. You are likely to notice this type of mucus when using toilet paper after urinating. If not, place your fingertip just inside your vagina to check the consistency and appearance of the mucus.

  • Levels of luteinizing hormone (LH) rise about 24 hours before ovulation. Levels of LH in urine can be tested using a home ovulation predictor kit. Note that you have to test levels of LH before it rises, since by the time it rises, most of the fertility window has passed. It is to test the levels on day 7 after your period starts, and again on day 10 or 12.

After you have determined the day of ovulation with the above tests, your fertility window is the same as described above, that is, the day of ovulation and 5 days prior to that.
