Irregular menstrual flow accompanied by a relatively large amount of blood-like discharge. Consider whether you are pregnant if you have a normal history of sexual life, or a sign of ovarian endocrine dysfunction if pregnancy is ruled out or if you have no sexual experience yourself. Simply a large amount of watery discharge, when women suffer from gynecological diseases such as uterine fibroids, ovarian cysts, pelvic inflammatory disease and cervicitis, can also cause a larger amount of watery discharge from the vagina. When the above symptoms appear, it is recommended to go to the gynecology department of a public hospital in a timely manner. Based on the menstrual cycle and sexual history, combined with early and early pregnancy tests, ultrasonography and sex hormone six tests, a comprehensive analysis should be conducted to clarify the specific causes and then deal with them.
