If . If the blood test was negative then you are not pregnant. You are dealing with amenorrhea. There are multiple causes of amenorrhea including hormonal changes, sudden increase or decrease in weight, stress/anxiety, medications, thyroid issues. My advice for you is to visit your primary care provider for a detailed evaluation. Your doctor may discuss the option of birth control pills to help regulate your cycle. Best of luck.
