If this is negative, your doctor will carry out tests to rule out high cholesterol, hormonal imbalance as seen in thyroid problems and PCOS, Cushing’s disease and disorders of adrenal gland, tumors of the ovaries and adrenals, insulin resistance and obesity
. Stress, chain smoking, and dramatic changes in your life style are the other causes
of irregular periods. So, before your consult take a blood test for pregnancy. Take care!
