What are some common ways to calculate a woman’s ovulation period
What is the menstrual cycle
The so-called menstrual cycle is a cycle that starts on the first day of the current menstrual period and lasts until the day before the next menstrual period, which is called a menstrual cycle, and generally lasts about 26-35 days. A woman’s menstrual cycle can be categorized into the menstrual period, the ovulation period (also known as the danger period) and the safe period.
What are the main ways to know the ovulation and safe periods
Calculating with known menstrual cycle
The method of projecting ovulation by the menstrual cycle is also known as the calendar method. Both menstruation and ovulation are affected by endocrine hormones from the pituitary gland and ovaries and show cyclic changes. The length of their cycles is the same, 1 cycle per month, while ovulation occurs in the middle of two menstrual periods.
A woman’s menstrual cycle may be long or short, but the interval between the day of ovulation and the start of the next period is relatively constant, usually around 14 days. Based on this relationship between ovulation and menstruation, it is possible to calculate ovulation according to the menstrual cycle. Calculation method is from the first day of the next menstrual period, counting down 14 days or minus 14 days is the day of ovulation, the day of ovulation and its first 5 days and the next 4 days together is called the ovulation period. This is the theoretical basis of the safe period contraceptive method.
However, this method can only be applied to women with normal menstrual cycles. For women with irregular menstrual cycles, since they are unable to predict the date of their next menstrual period, they are unable to predict the safe period and ovulation, but they can use the following methods to measure.
Measurement of Basal Body Temperature
The basal body temperature of a normal woman of childbearing age varies cyclically, just like the menstrual cycle. This change in body temperature is associated with ovulation. Under normal circumstances, a woman’s basal body temperature is low before ovulation and rises after ovulation.
Body temperature should be measured every morning as soon as you wake up, try to keep your body from moving, keep it every day, and observe it dynamically. When the body temperature suddenly drops one day and then rises again the next day by 0.3-0.5 degrees, it means that you are about to ovulate or are in the process of ovulation, i.e., the high-risk period.
Ovulation test paper
Ovulation test strips are not just for measuring the day of ovulation! In a normal woman, if she is pregnant this month, she will definitely get 2 positives, or even strong positives, on the ovulation test this month! The first time is when ovulation occurs, i.e. in the middle of a menstrual cycle, and the other time is within 7 to 10 days afterward.
If the test is negative you can test every other day, if there is a weak positive you need to test every day, if there is a strong positive it means that ovulation is going to happen within 24-48 hours. Generally, the strong positive test lasts for 2 days, and when the test turns from strong positive to negative, it means that ovulation has occurred.
