Frequently Asked Questions
Is ovulation always on day 14?
No. It depends entirely on your cycle length. Day 14 is average for a 28-day cycle, but it varies for longer or shorter cycles.
Can this help avoid pregnancy?
While it tracks fertile days, it is not a foolproof contraceptive method (rhythm method) as cycles can fluctuate unpredictably.
Does stress affect ovulation?
Yes. High stress, illness, excessive exercise, or significant weight changes can delay or temporarily stop ovulation.
Can irregular cycles use this?
This tool uses averages. If your cycles vary by more than a few days each month, the results may be less accurate. Consult a doctor.
