red/orange bleeding during period

My Period usually comes every 24-25 days and lasts for about 4-5 days with bad cramps on the first two days. Its usually very heavy and dark in color. However, this time my period came 4 days late and I have been cramping for a week now. I, as well had reddish/orange bleeding.. I am confused and worried as well... did you find out what was going on with you... is that normal?

Thanks
