When is ovulation?

What is the principle of calculating the safe period for women? Under normal circumstances, women's ovulation date at this time is when the next menstruation comes, usually about two weeks before the onset of menstruation. Counting back fourteen days from the first day of the next menstrual period, or subtracting two weeks, is the female's ovulation day. Let's take a look at when is the ovulation period.

When does the ovulation period come? In fact, a woman's ovulation day is a total of five days before and four days after, which is the ovulation period on that day. In addition to the menstrual period and the ovulation period, other times are considered safe periods. This is the knowledge of when is the ovulation period, we must understand it.

As the pace of modern life continues to accelerate, women are increasingly affected by the real environment. In addition, women's emotions, diet, lifestyle habits, etc. all affect their ovulation. When a woman with a relatively regular life rhythm suddenly changes her life rhythm, her menstrual period may be advanced or delayed, and the length of the ovulation period will fluctuate with the change in the menstrual period. Therefore, the ovulation period of 10 days is an approximate statement, but in fact, the ovulation period of women is generally less than 10 days.

Since the ovulation period is not necessarily a fixed ten days, how long is the effective pregnancy time if you have sex during the ovulation period? Generally speaking, the survival time of a normal woman's egg is about 2 days, up to 3 days, and less than 12 hours. A man's sperm can generally survive in a woman's body for 3 to 5 days, usually 4 days.

As for when is the ovulation period, in fact, the effective conception time during a woman's ovulation period is five days before ovulation, because at this time the sperm can survive in the female body for about five days, and two days after ovulation, because after the egg is released, it can only survive in the female body for about two days. In other words, the effective conception time is seven days.
