  • Calculate ovulation by counting 14 days before your expected period, regardless of cycle length.
  • Track basal body temperature to identify ovulation patterns, especially with irregular cycles.
  • Monitor cervical mucus changes - it becomes thick and increases right before ovulation.
  • Time conception attempts 2-3 days before your basal body temperature rises for best results.
  • Use multiple tracking methods together for more accurate ovulation prediction.

Ovulation occurs 14 days before your next period starts, regardless of cycle length. In a typical 28-day cycle, this means day 14, while longer cycles shift the timing accordingly. Track basal body temperature and cervical mucus changes to accurately calculate your ovulation window.

Let's talk about ovulation

Conception occurs during ovulation, which happens about two weeks before the start of menstruation. In a 28-day cycle, ovulation occurs on the 14th day. If a woman has a 36 day cycle, ovulation occurs on the 22nd day. The period from the day of ovulation to the end of the cycle is always 14 days [1].

During ovulation, a woman’s basal body temperature increases. Conception is most likely to occur two to three days before this temperature increase. If you have an irregular cycle, tracking your basal body temperature can help you predict ovulation [1].

From the moment of conception, your body starts working to create new life. This work is mostly imperceptible, though an increase in progesterone can be responsible for things like mood changes and fluid retention.

Discharge

Immediately before ovulation, the amount of mucus secreted by the cervix increases, and the mucus itself becomes thick and viscous [1].
