If you plead guilty without going to court in August of 2012, then you were probably convicted.
If you received another speeding ticket since then, and plead guilty, your license will likely be suspended under the 2 in 24 rule (2 convictions in 24 months will suspend your license).
I recommend seeking an attorney so that you can negotiate for a disposition of "Court Supervision", which does not count as a conviction.
