Hello ma'am.Brown spotting
or discharge is either normally present before a period begins or when it ends. It is otherwise also present during pathological conditions like infections, miscarriages and hormonal
imbalance. Please consult your doctor at your earliest convenience as you are also experiencing itching around the genitals, which is also a symptom of an infection.
In the meantime, please abstain from all forms of sexual contact. I hope this helps.
