Many couples find it difficult to conceive, and it is perfectly normal to face challenges. This is because ovulation only occurs once per menstrual cycle, and the chance of pregnancy is limited to a short few days. This period is known as the “fertile window.” Since this window is so brief, it makes sense that getting pregnant can be tricky. To improve your chances, the key is to identify your own fertile window.


What is Ovulation?

Ovulation is the process when an egg is released from a follicle in the ovary. Ovulation typically occurs 12 to 18 days (on average 14 days) before the next menstrual period begins.


How to Know When Ovulation Happens?

To estimate your ovulation, you first need to know the timing of your next menstrual period, which means you should understand your menstrual cycle.

  • Menstrual cycle: The length of your cycle is the number of days from the first day of your previous period to the day before your next period starts. A typical cycle lasts about 28 days, though 24 to 34 days is also considered normal.
  • Ovulation in a 28-day cycle: If your cycle is 28 days long, ovulation likely happens around Day 14 (28 – 14 = 14).

What If Your Cycle is Irregular?

If your cycle is irregular, predicting ovulation can be tricky. Here are some methods to help you:

  • Check Cervical Mucus:
    Before ovulation, cervical mucus becomes clear, slippery, and stretchy, resembling raw egg whites. This change creates an ideal environment for sperm to pass through the cervix. Your body is signaling that it’s the best time to try for pregnancy. After ovulation, the mucus changes—becoming thicker, white or yellow, making it harder for sperm to move through the cervix.
  • Use Ovulation Test Strips:
    Ovulation test strips detect the surge in luteinizing hormone (LH) that occurs right before ovulation. If the test is positive, ovulation will likely occur within 24 to 48 hours.

How to Identify Your Fertile Window?

The fertile window lasts approximately 6 days: from 5 days before ovulation to the day of ovulation.

  • If you have intercourse more than 6 days before ovulation, the chance of getting pregnant is nearly 0%.
  • If you have intercourse 5 days before ovulation, the chance of pregnancy increases to 10%.
  • The chances increase significantly 2 days before ovulation and on the day of ovulation.

How to Increase Pregnancy Chances During the Fertile Window?

To improve your chances of natural conception, it is recommended to have intercourse at least once every 2 days during the fertile window.

  • If your ovulation is difficult to predict (e.g., due to irregular periods), or if tracking ovulation is inconvenient, you can have intercourse every 2 to 3 days throughout the cycle. This approach ensures you cover the fertile window and increases your chances of getting pregnant.
