What is Ovulation?

Ovulation is the release of a mature egg from the ovary, typically occurring about 14 days before the start of your next menstrual period in a 28-day cycle. This egg is then available for fertilization for a short window, usually 12-24 hours. Understanding ovulation signs helps you identify your most fertile days.

Methods to Track Ovulation

Several methods can help you estimate your ovulation period:

  • Menstrual Cycle Tracking: The simplest method is to track your menstrual cycles. If you have a regular cycle, ovulation tends to occur around the same time each month.
  • Basal Body Temperature (BBT): Your BBT is your temperature at rest. It slightly increases after ovulation. Tracking your BBT over several months can reveal a pattern.
  • Cervical Mucus Monitoring: The texture of your cervical mucus changes throughout your cycle. It becomes clear, slippery, and stretchy (like egg whites) just before ovulation to help sperm reach the egg.
  • Ovulation Predictor Kits (OPKs): These kits test your urine for luteinizing hormone (LH), which surges 24-36 hours before ovulation. These kits are available at most pharmacies.

Factors That Can Affect Ovulation

Several factors can impact ovulation:

  • Stress: High stress levels can disrupt hormone balance and affect ovulation.
  • Weight: Being underweight or overweight can impact hormone production and ovulation. Maintaining a healthy weight may help.
  • Medical Conditions: Conditions like PCOS (Polycystic Ovary Syndrome) and thyroid disorders can interfere with regular ovulation.
