How to calculate the ovulation period for women

In fact, women's ovulation period is usually calculated acutely based on their own menstrual period. The average female menstrual cycle is four weeks, or 28 days. If we calculate based on the day of the last menstrual period, ovulation will occur on the 14th day. This calculation method is relatively simple. If you want to prepare for pregnancy, in addition to the ovulation time, you also need to regulate your body.

1. Infer ovulation period through menstrual cycle records

The menstrual cycle of women all over the world ranges from 21 to 35 days, with an average of 28 days. Generally speaking, as long as it is a regular, normal menstrual cycle with ovulation, the luteal phase of menstruation after ovulation is relatively fixed, which is 12 to 16 days, with an average of 14 days. The period before ovulation is called the follicular phase, and its duration varies depending on the length of the cycle, but the luteal phase after ovulation is basically the same, which is 14 days. Therefore, if you have a regular and normal menstrual cycle and your cycle is 21 days, you may ovulate on the 6th or 7th day of your cycle. If your menstrual cycle is 35 days, you may ovulate on the 20th or 21st day.

2. Basic body temperature detection

A biphasic body temperature indicates ovulation; if there is no high-low change in body temperature, it is called a monophasic body temperature, which is usually a non-ovulation body temperature. If the body temperature rises after ovulation and remains for about 12 to 14 days, it means that the corpus luteum is functioning well. Since there are many factors that affect changes in body temperature, if you use the basal body temperature method, you must insist on measuring it every day, especially when approaching the ovulation period. Draw a curve on the basal body temperature chart. Generally, you should measure it continuously for at least 3 menstrual cycles before you can summarize your own ovulation pattern.

3. Observation of cervical mucus

The specific operation is to start daily observation and recording from around the 10th day of the menstrual cycle. For the few days after menstruation, it is enough to just have an impression, and there is no requirement to start immediately after menstruation. Every time you go to the bathroom, check your sanitary pad to see how much secretion is on it and whether there is any particularly clear mucus. These translucent parts are mainly composed of cervical mucus. You can use your index finger to dip in the transparent mucus, then use your thumb to pull it apart to see how long the stretch is. If it is more than 8cm, it is close to ovulation. If it is more than 12cm, ovulation should occur within 24 hours. Of course, considering the individual differences of each person, it is recommended to use personal measurement data as the standard.

The above is an introduction to the method of calculating women's ovulation period. In short, whether for pregnancy or contraception, it is important to develop a good habit of recording your menstrual cycle. In addition, the ovulation date cannot be determined simply by calculating based on the menstrual cycle. Especially women with irregular menstrual cycles and difficult to predict the date of their next menstrual period must resort to other methods.
