Thanks for posting query.
In this context, reasons for irregular period or spotting are hormonal
imbalance, stress/ anxiety
, wt gain/extreme loss, irregular eating habits, psychological factor etc.
One cycle irregular spotting is nothing so important. But in persistent cases, she may require some investigations to rule out underlying pathology through USG pelvis scan, thyroid
profile & other hormone assay etc. Consult with your gynecologist and take suggestive measures.
Avoid stress / anxiety by regular deep breathing, take healthy diet with vitamin & iron supplements
, eat more fruits & vegetables , drink plenty water or juice and maintain genital hygiene properly.
