Why did i miss 8 months of a period im not pregnant and never been pregnan had blood tests thay came back clear av since but ive at 2 in month on my 2nd one this after missing 8?

There are many potential causes for missing 8 months of a period besides pregnancy. Some common causes include:

- Hormonal imbalances: Conditions such as polycystic ovary syndrome (PCOS) or thyroid problems can disrupt hormone levels and affect the menstrual cycle, leading to irregular or missed periods.

- Stress: Chronic stress can disrupt the hypothalamus and pituitary gland, which are involved in regulating the menstrual cycle.

- Weight loss or gain: Sudden and significant changes in body weight can affect hormone levels and menstrual regularity.

- Certain medications: Some medications, such as birth control pills, antidepressants, and chemotherapy drugs, can affect the menstrual cycle.

- Medical conditions: Some medical conditions, such as diabetes, chronic kidney disease, and certain types of cancer, can affect hormone levels and menstrual function.

It's important to note that having two periods in one month after missing 8 months does not necessarily mean that your cycle has returned to normal. It's always a good idea to consult with a healthcare provider to determine the cause of your missed periods and to ensure your overall health and well-being.
