I took off the nuvaring 6 hours later then when I supposed too and after the 7 days free(today) I?

If you're doing 3 weeks in and one week out you should be ok. The ring is good for 4 weeks. That means the late taking it out won't matter, and since you took it out late, and were covered then putting it in later then usual is still only the same amount of time out so you're ok.
