Wait and see. Most of the posters on this forum are geno 1's and a brief tx like yours would never work for us. As a 3 you are much more responsive to the treatment and had a lower VL. It is NOT impossible that you cleared and can stay clear with only 7 weeks of TX, just puts you in a rare situation. Good for you. You may end up to be a very lucky guy who has removed the virus completely from the body in a record short time. Let your doctor take the lead.
The Virus usually comes back the first month after stopping treatment. So if I understood your post correctly you were still Virus free 6 weeks after stopping treatment. If this is the case you should be good to go. Just get a 3 month and 6 month post treatment PCR to be sure.

If you are saying that you stopped the treatment meds on 6/18 and had an undetectable pcr on 8/5 I'd suggest to listen to your doctor and don't do anymore - yet. I'd wait another month or two, get another pcr then and make a plan. It is possible that you could have achieved svr with that abbreviated treatment. The definition of svr is no detectable virus after 24 weeks of treatment end. But, if you are undetectable 3 months after stopping you should be pretty optimistic.
