Troubles with bowels

For the past 2 months I have been having weird things going on with my bowels.. At first I was going to the bathroom frequently in small amounts with red/orange tinged mucus separate from the stool, this happened about once a week for 4 weeks. So I started taking fibre supplements and it made it better, but I still have extra whitish mucus sometimes. Lately I have been extremely constipated with small amounts of stool at a time. Has this happened to anyone else? Or anyone know what it may be?
