I took mifepristone and misoprostol according to the way it was prescribed....i bleeded for six days after but stopped and continue's after five days what could be the reason? could i be still pregnant?

The agents used in your question do not always cause a complete abortion, and remaining tissue in the uterus may cause persistent bleeding. See your GYN physician who prescribed the medications, for further testing (ultrasound), however pregnancy outside the uterus (ectopic) may also be the cause, so obtain a serum HCG test for low levels of pregnancy hormone, and follow up with your MD.
