The best time for hysteroscopy is 1-3 days after the menstrual period is clean. For patients with dribbling menstrual periods that take more than ten days to clear can choose 8-12 days of the menstrual cycle, because many patients with endometrial polyps, themselves show prolonged and dribbling menstrual periods, often some of them take more than ten days to clear, and even some of them take half a month to clear. If you wait until the period is completely clean, the endometrium has already proliferated and is in a state of secretion. If the hysteroscopy is performed again, what you see will not be the real normal shape of the uterine cavity. Therefore, it is generally recommended that the hysteroscopy be performed on the sixth day of menstruation. You can make an appointment with your doctor, who will choose a specific time according to the patient’s specific situation. If the period is prolonged, by the seventh day of menstruation, in fact, the amount of menstruation has been very small, only there should be a coffee-colored discharge, the bleeding is always clean, this time can also be carried out hysteroscopy. So on the sixth day of menstruation, first of all, you can make an appointment with the doctor, describe the menstrual situation to the doctor, if the amount of menstruation has been significantly reduced, for example, pads can be, then you can choose the hysteroscopy of the examination, generally hysteroscopy can not be more than the tenth day of the menstrual cycle. This place we have to give you an introduction to what is called the menstrual cycle, sometimes with the patient to explain in the menstrual cycle of the tenth day or less should be called to make an appointment, but often some patients menstruation for half a month, and wait until a week clean to contact the doctor, said I came to do hysteroscopy, this time from the menstrual cycle counting, it has been to the 21st day, certainly can not be done hysteroscopy, this time is not a normal uterine cavity, but also the uterus, the uterus, the uterus and the uterus, the uterus and the uterus. The uterine cavity would not be in its normal shape at this time. The first day of the menstrual cycle refers to the first day of menstruation, not the first day of clean menstruation, which is a problem that we should pay attention to.
