Just to be clear in your 19 June post you said you were on day 8 which means your treatment start date was 11 June.

If (**If**) those dates are accurate then
6/11 - 6/18 week 1
6/25 week 2
7/2 week 3
7/9 week 4
In many cases the VL on week 4 determines treatment duration.
I do not want to assume too much or mislead you what with so little info but since you are stage 4 are you treating 48 weeks? In most cases with Incivek the treatment duration holds that if you are detected on week 4 you treat for 48 weeks anyway.
It would help to confirm or correct these dates and indicate whether you are treatment naive and whatever other info might help.
This is an older chart but here is the gist of it
