What Causes Orange Colored Bleeding During Periods In Person With Hpv?

Im on my period and its an Orange color. I noticed the same color towards the end of my period last month. Just wondering why it would be Orange. I'm 31yrs old, 4 ft 11 and weigh 94 lbs. I do have hpv,the one that causes cancer. I just had my 6 months pap and still waiting for the results.
