Women who want to know if they are ovulating can do so by the following methods: the first is to monitor ovulation by ultrasound, which is the most accurate method. Ultrasound is able to visually observe the development and discharge of the patient’s follicles. The second method is to monitor the basal body temperature. If the patient has a biphasic temperature, the temperature can rise by 0.3-0.5℃ within 1-2 days and can drop by 0.3-0.5℃ before menstruation. This situation mostly indicates that the patient is ovulating. Thirdly, ovulation can be monitored by using ovulation test paper. Patients can also choose to start monitoring from the first day of their first period, and when a strong positive test appears, it mostly means that the patient is ovulating. Fourthly, clinical symptoms can be observed, for example, the patient may have clear, stretched leucorrhea during ovulation, and individual patients may have ovulation pain or breast tenderness and other special manifestations during ovulation.
