Two months after diagnostic curettage, the menstrual flow is not as long as possible due to intrauterine infection, functional uterine bleeding, endometrial lesions, etc., which need to be analyzed specifically. 1. Intrauterine infection: If you don’t pay attention to cleanliness after diagnostic curettage or have sex too early, it may lead to infection in the uterus, which is manifested as irregular menstruation. 2. Functional uterine bleeding: after diagnostic curettage, if the original pathological factors are not removed, and endocrine disorders still exist in the body, such as functional uterine bleeding, it is possible that menstrual dribbling will occur again. 3. Endometrial lesions: after diagnostic curettage, if the endometrium has abnormal hyperplasia or develops into malignant lesions, it may also lead to persistent menstruation. Two months after diagnostic curettage, there may be other reasons for menstrual bleeding. It is recommended to go to the hospital in time, complete the examination to clarify the cause of the disease, and then give targeted treatment or therapy under the guidance of the doctor.
