Hello Good Evening, You might be pregnant, or suffered from irregular menstruation. Your pregnancy can not be clearly denied without a USG and repeat urine pregnancy test. You have missed period, which is due to some common reason like: -Pregnancy -Menopause -Stress and anxiety -Excessive weight loss, or weight gain -Hormonal imbalance -Hypothyroidism -PCOS Menopause is not applicable in your case and pregnancy should be rule out but any of rest of the others can be a cause for your missing period, so please go through proper evaluation to get other causes like hypothyroidism or PCOS. PCOS (Polycystic ovary syndrome) produces symptoms in approximately 5% to 10% of women of reproductive age (12–45 years old). It is thought to be one of the leading causes of female sub-fertility and the most frequent endocrine problem in women of reproductive age. The principal features are anovulation, resulting in irregular menstruation, amenorrhoea, ovulation-related infertility, and polycystic ovaries; excessive amounts or effects of androgenic (masculinizing) hormones, resulting in acne and hirsutism; and insulin resistance, often associated with obesity, Type 2 diabetes, and high cholesterol levels. The symptoms and severity of the syndrome vary greatly among affected women. So go for a USG, TSH and other investigation to find out the cause of amenorrhoea. Regards, Dr. Naresh Jain.
