Understanding Ovulation and Fertility

What is Ovulation?

Ovulation is the process where a mature egg is released from the ovary and travels down the fallopian tube, where it can be fertilized by sperm. This typically occurs around day 14 of a 28-day menstrual cycle, but can vary depending on your individual cycle length.

Signs of Ovulation

  • • Changes in cervical mucus (clear and stretchy)
  • • Slight increase in basal body temperature
  • • Mild pelvic or abdominal pain
  • • Increased libido
  • • Light spotting

Fertile Window

Your fertile window includes the 5 days before ovulation and the day of ovulation itself. Sperm can survive in the female reproductive tract for up to 5 days, while an egg is viable for about 12-24 hours after ovulation.

Tips for Conception

  • • Have regular intercourse during your fertile window
  • • Track your cycle for several months
  • • Maintain a healthy lifestyle
  • • Consider ovulation predictor kits
  • • Consult with a healthcare provider

Important Note

This calculator provides estimates based on average cycle patterns. Individual cycles can vary, and factors like stress, illness, or hormonal changes can affect ovulation timing. For the most accurate tracking, consider using additional methods like basal body temperature monitoring or ovulation predictor kits, and consult with a healthcare provider for personalized advice.
