Hello dear I understand your concern Missed period by one moth is not normal. Most common cause of missed period in the sexually active women is the pregnancy. I would suggest to go for blood HCG and USG scan for accurate confirmation of the pregnancy. If it will come negative then pregnancy is rule out. Following are the sign and symptoms of the pregnancy: breast engorgement and enlargement, darkening and enlargement of the areola, heaviness, increased frequency, nausea, dizziness, fatigue etc.. In absence of the pregnancy, other causes of the delayed period should rule out like thyroid dysfunction, hormonal imbalance, stress, ovarian cyst/PCOS, endometriosis, adenomyosis. Rule out the above causes by proper investigations like reproductive and thyroid hormone analysis, USG scan. Treatment will depend on the cause. Avoid stress, do regular exercise, take healthy diet, green leafy vegetables and fresh fruits. Hope this may help you Contact HCM for further health query Best regards Dr. Sagar
