Understanding Ovulation
What is Ovulation
Ovulation is the process where a mature egg is released from the ovary and becomes available for fertilization. Understanding your cycle is crucial for family planning.
Timing & Duration
Ovulation typically occurs 12-16 days before your next period. The egg is viable for 12-24 hours, while sperm can survive up to 5 days in the reproductive tract.
Signs of Ovulation
Look for changes in cervical mucus (clear and stretchy), slight temperature rise, mild pelvic pain, breast tenderness, and increased libido.
Fertility Window
Your most fertile days are the 5 days before ovulation and ovulation day. This 6-day window offers the best chances for conception.
