Women who are already preparing for pregnancy may be more concerned about ovulation day, as having sex during ovulation can greatly increase the chances of pregnancy. However, many women lack a certain scientific understanding of how to calculate and determine ovulation dates, and can only rely on intuition to guess, with a significant margin of error. So, from which day does ovulation start?
The ovulation date is often calculated from the day of the next menstrual period. Although most women have their periods every month, the actual number of days between periods varies greatly among individuals. However, the time interval between ovulation and the next period is usually fixed, usually around fourteen days. Therefore, when calculating the ovulation day, the estimated time of ovulation can be obtained by reversing the next menstrual period by fourteen days.
However, in reality, the ovulation date estimated by this method may not be accurate, so most of them estimate the ovulation period. The ovulation period is the sum of the estimated five days before ovulation and four days after, for a total of ten days. This period is called the ovulation period, during which the chance of conception during sexual intercourse is high.
In addition, eggs can survive in the female body for two to five days after being released, while sperm can survive for one to three days after entering the female body, so women should pay attention to arranging sexual intercourse time. To accurately determine the ovulation day, ovulation test strips can be used, or temperature can be continuously measured during ovulation, or ovulation monitoring can be used for observation, which has higher accuracy.
