Understanding Ovulation
Ovulation occurs when an egg is released from the ovary, typically 14 days before your next period. The egg survives 12-24 hours, but sperm can survive up to 5 days, creating a fertile window of about 6 days.
Signs of Ovulation
Common signs include increased cervical mucus (egg-white consistency), slight temperature rise, mild pelvic pain (mittelschmerz), increased libido, and breast tenderness.
Tracking Methods
Track your cycles for several months for better predictions. Ovulation predictor kits detect LH surge 24-36 hours before ovulation. Basal body temperature tracking shows ovulation after it occurs.
