Calculate your ovulation date and fertile window
Our comprehensive Ovulation Calculator helps women track their menstrual cycles and identify their most fertile days for conception planning. This essential tool provides accurate ovulation predictions, fertile window calculations, and personalized recommendations for optimal family planning and reproductive health management.
Most fertile day
Best conception time
Cycle prediction
Enter the first day of your last menstrual period and your average cycle length. The calculator will automatically determine your ovulation date, fertile window, and next period prediction. Use these results to plan conception attempts or to track your reproductive health.
Short Cycles (21-24 days):
Long Cycles (30-35 days):
Remember that every woman's cycle is unique, and variations are normal. The ovulation calculator provides estimates based on averages, but your actual ovulation may vary. Combine calendar tracking with physical signs like temperature changes and cervical mucus for the most accurate fertility prediction. Don't become overly stressed about perfect timing - the fertile window gives you several days for conception attempts. Focus on maintaining good overall health and reducing stress, as these factors significantly impact fertility. If you're having trouble conceiving, don't hesitate to seek professional help early.
