When a period goes away for a few days and comes again, it may be ovulatory bleeding or irregular vaginal bleeding, which should be distinguished. Great aunt is menstruation, which comes again within a short period of time after the end of menstruation and may be due to ovulatory bleeding if it is close to ovulation. Its due to the rupture of the follicle when estrogen rises in the blood followed by a brief drop in estrogen levels, resulting in the shedding of the endometrium and causing bleeding, which manifests as a small amount of vaginal bleeding. If it is not ovulation and there is still irregular vaginal bleeding after 7 days of menstruation, it may be caused by bleeding just after menstruation and the endometrium has not been fully repaired and stimulated by intercourse; it may also be abnormal vaginal bleeding caused by uterine fibroids, endometrial polyps and cervical polyps. Such patients need to go to the hospital for examination and treatment for the primary disease in time. In addition, patients are advised to maintain a good mood and avoid anxiety; pay attention to perineal hygiene and warmth, and do not eat cold and stimulating food.
