Malunga nale Calculator
An ovulation calculator estimates your most fertile days from the first day of your last period and your average cycle length. Ovulation typically occurs about 14 days before your next period, and the fertile window spans the five days before ovulation plus the day itself, because sperm can survive several days. Cycle-based estimates are a guide, not a guarantee.
The tool counts forward from your last period. On a 28-day cycle, ovulation lands near day 14 (28 − 14) and your next period around day 28. Change the cycle length and it moves accordingly: a 30-day cycle puts ovulation near day 16, since it always sits about 14 days before the next expected period. The fertile window it shows runs from five days before ovulation through ovulation day.
Use it to time intercourse when trying to conceive — the days leading up to ovulation are the most fertile — or simply to understand your cycle. It also projects the next few cycles so you can plan ahead. Because ovulation timing varies month to month, especially with irregular cycles, treat the dates as an estimate rather than reliable contraception or medical advice.
