Patient's question:
Age: NulliparousDetailed medical condition and consultation purpose: Menstrual cycle is longer, exceeding 38 days. In recent times, there have been three instances of slightly abnormal menstruation. Two days before menstruation, there is a small amount of dark red discharge (similar to very faint blood), which gradually turns red, and by the third day, menstruation begins as usual. I would like to know if the dark red discharge is considered the start of menstruation?
First follow-up question: In my case, when calculating the ovulation period, should I count backwards 14 days from the day when red discharge appears?
Doctor's answer:
Generally, brownish vaginal discharge in the 1-2 days before and after the end of menstruation is a normal phenomenon, but the causes are different. Brownish discharge before menstruation is caused by the shedding of a small amount of endometrium, while brownish discharge after menstruation is due to blood remaining in the reproductive tract for too long. If there is a small amount of vaginal bleeding between two menstrual periods, it is often considered ovulation bleeding. During the mid-cycle, a temporary decline in estrogen levels causes the endometrium to lose hormonal support, leading to partial endometrium shedding and regular vaginal bleeding. If there are no symptoms such as abdominal pain, yellow leukorrhea, odor, or external genital itching, it can be observed without excessive concern. Daily cleaning of the external genital area with warm water, maintaining dryness and hygiene, and preventing infection can be helpful. However, it is also possible that it is caused by gynecological conditions, such as cervicitis or vaginitis. A gynecological examination and colposcopy can be performed to identify the bleeding site and determine if the bleeding is abnormal.
