What is the ovulation date for the aunt who came on the 14th?

Ovulation occurs on the 14th

day before the next menstrual cycle, and 5 days before ovulation, 4 days after ovulation and the day of ovulation, a total of 10 days of time for ovulation. If calculated according to a month of 30 days, then for women with a menstrual cycle of 30 days, the ovulation day is usually on the 30th of this month, and on the 25th of this month-the 4th of the next month is ovulation. However, due to the different menstrual cycles of each woman, coupled with the different days of each month, there can be differences in the specific ovulation period. In addition, it should also be noted that for women with irregular menstrual cycles, due to the uncertainty of ovulation days, it is usually impossible to determine ovulation period.
