Two months without menstruation and no pregnancy through examination may be caused by the following reasons: 1. Endocrine disorder, due to stressful work or sudden environmental changes, resulting in endocrine disorder. If the endometrium is found to be significantly thickened by ultrasound, with a thickness of more than 1cm, you can drink a bowl of hot brown sugar motherwort water every day, which has the effect of promoting menstruation, for 3 consecutive days to see if you will get your period. 2. It may be caused by an increase in prolactin, such as a common pituitary microadenoma that raises prolactin, so it can cause no menstruation. The clinical examination often reveals microadenomas in the pituitary gland, and after medication or surgery, menstruation will be restored. 3. Menopause caused by polycystic ovary syndrome can be clearly diagnosed through examination, and systematic treatment will restore menstruation to normal.
