If first three days of haiz(periods) are continue and on fourth and fifth day there is no blood and on sixth day there is a little bit of blood, Is it haiz for all the six days. Can i do gussal after 3 days or 6 days?

If for three complete days there is continuity of blood, then if it stops on 4th and 5th day, on these days she will take ghusl and pray based on obligatory precaution and then on the 6th day when blood resumes, she has to follow the rules of haydh again and then do another ghusl when blood stops
