Frequently Asked Questions (FAQs)

How does this period calculator work?
This tool uses the start date of your last period, how long your period lasted, and your average cycle length to calculate your next period, ovulation day, and fertile window. It follows standard fertility logic combined with Ayurvedic principles for natural cycle tracking.
How many days after my period can I get pregnant?
You’re most likely to get pregnant if you have intercourse during your fertile window—typically 5 days before ovulation plus the day of ovulation, which usually happens around 12–16 days before your next period starts.
What are the fertile days after a period ends?
Fertile days usually start about 9–10 days after your period begins, depending on your cycle length. This calculator will give you exact predicted fertile days to increase your chances of natural conception.
How accurate is this period and ovulation calculator?
If your cycles are regular, this calculator provides a highly accurate prediction. For irregular cycles or PCOS, it gives an estimate—but we recommend consulting a doctor for a personalized diagnosis.
What is the best time to get pregnant after a period?
The best time to try is during your fertile window, especially 2 days before ovulation and on ovulation day . This is when your egg is most likely to meet healthy sperm.
What if my periods are irregular?

How do I know if my period is late?
