, reasons of irregular / late period could be PCOD, hormonal
imbalance, over weight/ extreme loss, mental stress, emotional upset, eating disorder
, thyroid problem etc.
Therefore, I suggest to undergo one USG lower abdomen and hormone test in the absence of pregnancy. Kindly, consult with your gynecologist and take advice accordingly. Combined hormonal pill is quite effective to treat irregular period.
You should control body wt, avoid stress, take healthy low carbohydrate
diet with avoidance of fatty food and sleep properly.
