I don't know if you need support.
The only medical assistance I got was a test at week 4, plus chats with my local pharmacist who put up the $22,000 up front so I could get my meds that the government is funding (I'm in Australia and HCV drugs are being funded but the pharmacist has to pay up front and then get refunded).
A week 4 test would be good, for your peace of mind, but if you are feeling good, my non professional thought would be to just continue.
Diagnosed in 2004, had HCV for all my adult life. Until 2016!!!!
