Frequently Asked Questions

How accurate is the safe period calculator? +
The calendar method is approximately 76-88% effective with typical use. Accuracy depends on cycle regularity. Women with irregular cycles should use additional tracking methods like basal body temperature or ovulation predictor kits for better accuracy.
Can I get pregnant during my safe period? +
While the probability is lower, pregnancy is still possible during "safe" days, especially if you have irregular cycles or ovulate earlier/later than expected. Sperm can survive up to 5 days in the reproductive tract, so unprotected sex before ovulation can result in pregnancy.
What causes irregular menstrual cycles? +
Common causes include stress, significant weight changes, polycystic ovary syndrome (PCOS), thyroid disorders, excessive exercise, breastfeeding, and perimenopause. Certain medications and contraceptives can also affect cycle regularity.
How do I track ovulation naturally? +
Methods include monitoring basal body temperature (BBT) daily, checking cervical mucus changes (egg white consistency indicates fertility), tracking cervical position, using ovulation predictor kits (OPKs), and observing secondary symptoms like mittelschmerz (ovulation pain).
Is the safe period method right for me? +
This method works best for women with regular cycles (21-35 days) who are willing to track meticulously. It's not recommended for those with irregular periods, postpartum women, or those who cannot accept even a small risk of pregnancy. Consult your healthcare provider to discuss all contraceptive options.
