Yes, it is possible. Menstrual cycles are subject to many factors that occur to women throughout the cycle, so it's only logical that ovulation days vary from month to month. In women with 28 to 32 day menstrual cycles, ovulation is expected to occur between days 11 to 21.
Can ovulation day vary each month?
