Modern HIV blood tests produce reliable results after a month, so yes, a week was too early.
However, even if he did have HIV (which he very probably doesn't) and wasn't receiving treatment, and if he ejaculated inside you (which he didn't) you'd be looking at 'about' a one in a thousand chance of getting it. Without ejaculation, it's not going to happen.
But you're worried, and so testing may be needed to confirm this. The 'one hour' tests will be reliable after this time.
Your smoking is far, far riskier to you than any of this. (It kills more gay men than HIV does, for example.)
