not sure what you are asking?? if you cshould continue cycle past6 weeks?? is there a reason you are asking us that? is there an issue?? i.e. gyno, or no gains so far in 6 week??
Your cycle is fine.. basically, the way i am reading it you are doing
350mg test prop
350mg Tren A
400mg Test Enth/Cyp
there is nothing wrong with blending the tests like that.. i would imagine with that much test you should be seeing some really good gains.. but i see no mention of PCT or anything.. so i would say run your cycle ten weeks total, then wait two weeks and start PCT.. get your PCT sorted now so you have it ready by the end of your cycle.
