When does ovulation occur during a 35-day menstrual cycle?

For women with regular menstruation, ovulation usually occurs about 14 days before menstruation; for women with irregular menstruation, it is recommended to monitor ovulation. There are many ways to monitor ovulation. The simplest one is to detect the body temperature during ovulation. This method requires women to measure their body temperature every morning when they wake up and do not engage in any activities.

Under the condition of very regular menstruation, women with a 35-day menstrual cycle will ovulate approximately 14 days before the next menstrual period, that is, around the 21st day after the menstrual period. However, for women whose menstrual periods are not regular, the ovulation period may also be irregular. If a woman only has a long cycle but the menstruation is regular, there is no need to worry. If a woman's menstrual cycle is irregular for a long time, it is recommended to find out the reason to avoid affecting pregnancy.

1. Generally speaking, women's ovulation period is 10 days.

A normal woman will ovulate once every menstrual cycle (usually one month). The day of ovulation is called the "ovulation period". The 5 days before ovulation, the 4 days after ovulation, plus the day of ovulation are called the woman's ovulation period. Therefore, women's ovulation period is 10 days.

2. Not everyone’s ovulation period is 10 days.

As the pace of modern life continues to accelerate, women are increasingly affected by the physical environment. In addition, women's mentality, diet, and lifestyle all affect their ovulation period. When a woman with a relatively regular rhythm of life suddenly changes her daily routine, if the body does not adjust in time, the endocrine state may be affected, and the menstrual period may be advanced or delayed. Then the length of the ovulation period will immediately fluctuate with the change of the menstrual period. Therefore, the ovulation period of 10 days is only an approximate time period, and in fact, the ovulation period of women is generally less than 10 days.

3. The reasonable pregnancy time during the ovulation period is 7 days.

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