I get a nose bleed every couple of days light ones should I be worried?

No. Most nose bleeds are benign and occur from an area near the opening of the nose. You try putting a small amount of Vaseline or other moisturizer in the nares. Be careful to avoid getting it into you lungs. See this site for more info. http://www.webmd.com/first-aid/nosebleeds-causes-and-treatments.
