Frequently Asked Questions
Q1: 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.
Q2: Can this help avoid pregnancy?
While it tracks fertile days, it is not a foolproof contraceptive method (rhythm method) as cycles can fluctuate unpredictably.
Q3: Does stress affect ovulation?
Yes. High stress, illness, excessive exercise, or significant weight changes can delay or temporarily stop ovulation.
Q4: 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.
