Ovulation test paper is used to test the level of luteinizing hormone in urine to determine whether a woman has ovulation. Generally, if the test paper is continuously monitored, it can change from weak positive to strong positive, and then to weak positive, indicating normal ovulation. If the ovulation test paper monitoring has been weakly positive, it indicates that the level of luteinizing hormone in the body is low, and there may be ovulation disorders. In addition, there is another situation that some women have a long menstrual cycle and ovulation time is relatively late. For example, patients with polycystic ovary syndrome may have this situation, or ovulation may not be monitored, and the ovulation test paper will always be weak positive. And the accuracy of ovulation test paper is not high. Therefore, if women want to accurately monitor whether there is ovulation, they can do vaginal ultrasound and pelvic ultrasound to monitor ovulation under ultrasound.
