I've had bad period pain feelings all day i'm not due on for 2 weeks and i'm not on any contraception, test says negative! i have health anxiety?

Health anxiety: It is not that uncommon for women to experience cramping as early as 2 weeks prior to the start of their period, usually when ovulating (sometimes called mittelschmerz). Other medical problems should be ruled out however. If you are preoccupied with health problems in general that cause you anxiety, therapy can be beneficial to get to source of your anxiety.
