I'm a 20 yr old female and my boyfriend and I always use the pullout method. I just recently had my period but it was a week early, lighter and less bleeding than usual, and instead of the normal reddish color, it was mostly brown. I'm wondering if this could mean I'm pregnant. My periods always arrive around the 20th of each month so I felt it was slightly weird that it came around the 2nd. Please tell me if you think I could be pregnant. Thanks.
