Thanks for the query.
During perimenopausal age group, due to hormonal
imbalance dryness of the genital mucosa can occur. That can bleed on friction.
But better to consult gynecologist once and get examined to rule out other causes bleeding.
If the cause is find out as purely hormonal, you can take local estrogen
cream with your doctor's advice that can relieve the symptoms.
