Frequently Asked Questions
How accurate is the ovulation calculator?
The calculator provides estimates based on averages. For most accurate results, track your cycle for 3-6 months. Factors like stress, illness, and lifestyle can affect ovulation timing.
What is Naegele's Rule?
Naegele's Rule is a standard way of calculating the due date. It adds 280 days (40 weeks) to the first day of your last menstrual period. The formula: LMP + 7 days - 3 months + 1 year.
Can I get pregnant outside my fertile window?
While it's possible, the chances are very low. Sperm can survive up to 5 days, and the egg survives for about 24 hours after ovulation. The fertile window is when conception is most likely.
How can I track my ovulation more accurately?
For more accuracy, track your basal body temperature (BBT) daily, monitor cervical mucus changes, use ovulation predictor kits (OPKs), and log your cycle length for several months.
