Do regular walking and exercise.
Eat healthy diet
Also note that
Menstruation required co ordinate action of various hormone that secreted by ovary (estrogen and
progesterone) and brain (FSH and LH).
If any above hormone is decreased or increased there is imbalance in menstruation.
So please do full hormonal profile : Estrogen, progestron, LH, FSH, HCG and thyroid hormone.
That help to diagnose hormonal imbalance.
After confirmation you can take treatment.
Hope this may help you
All the best.
Stay healthy.
