In Jewish law you are Jewish if your mother is Jewish. So long as you know that your mother and her mother (and her mother, etc.) isn't Jewish then you are not Jewish. There is no magical (or medical or any scientific way) to know if you're Jewish.
You may be. Technically, if your mother is Jewish you're Jewish. So, if your mother's mother was Jewish your mother was Jewish and you're Jewish.
