It is not recommended to check the color ultrasound when menstruation is coming because doing color ultrasound may affect the accuracy of the test results.
During menstruation, due to the presence of blood in the uterine cavity, it may not be possible to see the uterus and adnexa clearly during the color ultrasound examination, which may affect the examination results to some extent, and therefore color ultrasound examination is not recommended during menstruation.
If there is only a small amount of bleeding during menstruation, gynecological ultrasound can be performed with little effect. If the amount of menstrual blood is heavy, the accuracy may be affected when performing a vaginal ultrasound. Therefore, it is not recommended to perform color ultrasound without abnormalities during menstruation to avoid affecting the results.
If clinical symptoms are more obvious during menstruation, such as severe dysmenorrhea and increased vaginal bleeding, appropriate examinations should be performed as prescribed by the doctor.
