All About Ovulation

Knowing when you are going to ovulate, makes it easier to plan a pregnancy.

What Is Ovulation?

Ovulation is the process in which an egg (or sometimes more than one) is released from the ovary. This is the fertile phase of the menstrual cycle. Each month, an egg matures within the ovaries. Once it reaches a certain size, it is released from the ovary and travels through the fallopian tube toward the uterus.

When Exactly Does Ovulation Occur?

To estimate your ovulation date, count 12 to 14 days backward from your next expected period. For women with a 28-day cycle, ovulation often occurs on day 14.

You can use our Ovulation Calculator to get an estimated fertility window.

Fertility

The egg can survive for about 24 hours after ovulation, while sperm can live for several days. Therefore, to increase the chances of conception, intercourse should occur around the ovulation period—typically from two days before ovulation until 24 hours after it.

Having intercourse around ovulation significantly increases the likelihood of conception. In fact, for fertile couples, there is approximately a 20% chance of conception in each cycle. Around 85% of women who have unprotected intercourse will conceive within a year. Identifying the exact ovulation date can make the process easier.

Signs and Tracking Ovulation

Cervical Mucus Changes

Throughout the menstrual cycle, the consistency and quantity of cervical mucus change. A woman is most fertile when the mucus is clear, stretchy, and slippery (similar to raw egg whites).

Basal Body Temperature (BBT)

After ovulation, body temperature rises by 0.4 to 1 degree Celsius. Tracking your temperature over time helps detect a pattern. A woman is most fertile during the two days before the temperature peak. To predict ovulation, it’s recommended to track BBT for several months and have unprotected intercourse 2-3 days before the expected rise in temperature.

Lower Abdominal Discomfort

About 20% of women report mild discomfort or cramping during ovulation, lasting from a few minutes to several hours.

Ovulation Test Kits

Available at pharmacies, these kits detect a surge in LH hormone in the urine, which occurs 12-36 hours before ovulation.

Follicle Tracking

Eggs develop inside follicles within the ovaries. These follicles grow throughout the menstrual cycle until they rupture and release the egg (ovulation). Ultrasound monitoring can track follicle growth and detect ovulation. In addition, blood tests measuring progesterone levels help confirm ovulation.

To monitor ovulation using follicle tracking, regular ultrasound scans and blood tests are needed, typically every few days at a clinic.
