One week before menstruation, brown discharge in the vagina? 15 years old

Patient's question:

No

Doctor's answer:

Hello, as you described, it is common to experience slight bleeding before menstruation, which is usually caused by insufficient luteal function or premature atrophy, leading to a lack of progesterone and inability to maintain the stability of the secretory endometrium. If it occurs continuously, it should be taken seriously. Under the guidance of a doctor, you can use small doses of hormone adjustment or supplementation to improve luteal function. Wishing you good health.
