Common Questions
How accurate is ovulation tracking?
This calculator provides estimates based on average cycle patterns. Ovulation typically occurs 14 days before your next period. For precise tracking, combine this with ovulation predictor kits (OPKs), basal body temperature monitoring, and cervical mucus observation.
When is the best time to conceive?
The fertile window spans 5-6 days: the 5 days before ovulation and ovulation day itself. Peak fertility occurs 1-2 days before ovulation. Having intercourse every 1-2 days during this window maximizes conception chances.
What if my cycle is irregular?
Irregular cycles make prediction more difficult. Track your cycles for 3-6 months to identify patterns. If cycles vary by more than 7-9 days, consult a healthcare provider. Fertility tracking apps and devices can help with irregular cycles.
When should I seek medical help?
Consult a fertility specialist if trying to conceive for over 12 months (if under 35) or 6 months (if over 35) without success, or if you have irregular/absent periods, painful periods, or known reproductive health issues.
