The color of blood during period can be orange due to - mixing of white/mucous vaginal discharge along with blood, as a result would make it appear orange.
However,if you have any of these symptoms- fever, pelvic pain, excess vaginal discharge, then it may be sign of underlying infection. In such case, you need to be seen by doctor. If you have only , this orange blood , do not worry, and wait till your next period. Take care
