I Understand your concern Following are the cause of irregular period: Hormonal imbalance, emotional problem like stress, ovarian cyst/PCOS, change in life style and dietary habit, thyroid disorder etc. I advice you to consult the gynecologist and get the done following investigations: reproductive hormone analysis, thyroid hormone, ovarian follicle study, USG scan etc. Management depends on cause. Period can be induced by medroxyprogesterone after proper evaluation. Do regular exercise like walking and medication early in the morning for 45-60 minutes, healthy diet and fresh fruits. Hope this may help you Best regards hank you for writing to us. I have gone through your query with diligence and would like you to know that I am here to help. There can be various causes for an irregularity in your menstrual cycle, and I shall start by listing some of the most common causes for this: -Stress -Infections anywhere in the body (a raised white cell count suggest an infection, and in your case this could be the cause for the irregularity in periods) -Medications -Conditions like polycystic ovaries -Chronic conditions (e.g. diabetes, hypertension, etc.) -Birth control pills and various other causes As your white cell count is high, it is important to first find the cause for the raised white cell count (i.e. find the infection). Once the infection is found, we can initiate antibiotics which can help treat the infection. Once the infection has been treated, we shall observe your menstrual cycle to see if it is regular or not. If it is regular, the cause for your irregular periods was the infection. But if it is still irregular, then we will have to further investigate. But for now the aim should be to diagnose the infection, so we can accordingly initiate antibiotic coverage. I would thus urge you to discuss all this with your doctor, as a diagnosis can be made only after a physical examination.
