Hi, Welcome to Health care magic forum.
The pain during the period may be due to the infection, and irregularity in the period may be due to the infection, the discharge from the breast may be due to the Hormone imbalance
I advise you to consult a gynecologist for diagnosis and treatment. You may need to have hormone essay,and M.R.I. for diagnosis.
I usually prescribe to my patient with such symptoms fluconazole
Take more of green leafy vegetables, pulses, sprouts, and protein rich foods to have good health and resistance against infections.
Wishing for a quick and complete recovery. Thank you.
