What is the reason for dark brown period two days before menstruation?

There are many reasons why the dark brown color of the vaginal discharge may be caused by a small amount of menstruation or by a disease.

1. Non-disease factors: Some women bleed less in the first two days of menstruation due to insufficient qi and blood, changes in work and rest, abnormal mental state, etc., and a small amount of blood becomes dark brown after oxidation. It may also be that they have not paid attention to keeping warm recently or have eaten cold food, which causes menstrual blood to be dark brown, which may be accompanied by abdominal pain.

2. Disease factors: Luteal atrophy dysfunction, endometritis, endometrial polyps, etc. cause the endometrium shed during menstruation to be unable to be secreted and discharged well, resulting in reduced blood flow and dark brown color. Endocrine disorders and hormone level disorders may also cause dark brown blood in the first two days of menstruation.

If the color is dark brown two days before menstruation, don't worry too much. Pay attention to rest, keep warm, and eat a light diet, and it will generally return to normal gradually. If the symptoms persist for one or two months, you can go to the hospital for a B-ultrasound to determine the cause and treat it in time.
