Understanding Your Fertility

Ovulation Window

Ovulation typically occurs 14 days before your next period. The egg survives 12-24 hours, but sperm can live up to 5 days in the reproductive tract.

Best Time to Conceive

Your fertile window is the 6 days leading up to and including ovulation day. The highest pregnancy rates occur with intercourse 1-2 days before ovulation.

Tracking Your Cycle

Track your cycle length, basal body temperature, and cervical mucus changes to better predict your fertile days and improve conception chances.
