No. The timing of ovulation can vary from one woman to another and even within the same woman over time. In a typical 28-day cycle (measured from the first day of one period to the first day of the next), ovulation usually occurs around day 14, plus or minus two days.  

The post-ovulation phase, known as the luteal phase, is relatively stable, lasting about 14 days, This means that cycle variations mainly reflect differences in the time it takes for an egg to mature.  

- In a 24-day cycle, ovulation may occur around day 9 after the start of the period.  

- In a 60-day cycle, ovulation may happen much later, around day 45.  

As ovarian aging progresses, cycles tend to become shorter, leading to earlier ovulation. Because ovulation timing is unpredictable, the best way to maximize the chances of pregnancy is to have intercourse every three days, starting at the end of your period.
