The answer depends on whether your wife is a U.S. citizen or just permanent resident. If she is a citizen then you should have filed the I-485 at the same time as the I-130 and you would have been scheduled for an interview at the USCIS district office in LV and provided it all goes well, gotten your green card. (all this provided you were previously lawfully admitted to the U.S.) In case your wife is only a green card holder, then the I-130 was the first step, and you'll need to wait about 4 years until your priority date becomes current and you'll have an immediate immigrant visa number available to you .

What you haven't stated is your location. That, in large part, controls what happens next. If you are outside the U.S., you process through the consulate. If you are in the U.S. pursuant to a lawful admission, you may be eligible to adjust status. Perhaps its time to retain counsel.
