Hi,
Ovulation happens about two weeks before the next expected period. As you said, yours is a 30days cycle_you ovulate around day 16.
Remember the ‘fertile window’ is the six days leading up to and including ovulation.
The three days leading up to and including ovulation are the most fertile. Depending on your cycle length the most fertile days in the cycle varies
As you have 30 days between periods ovulation typically happens on day 16, and the most fertile days are days 14, 15, and 16.
