Not on pill, my boyfriend uses pullout meth. No std, having only brown spotting for my last 2 periods what is wrong??

HARD TO SAY. Without some basic testing and an exam it is hard to say. You state you have no STD, but unless you have been tested you are just guessing. Many can be present with little or no symptoms for months or years. By the way, the "pull out method" is not birth control.The excited penis leaks sperm containing fluid constantly which can get you pregnant.
