Could have been a regular dream, in which you were thinking about lucidity. But if you at any time realized you are dreaming, then that part was lucid.

After we practice RCs, they may start showing up in our dreams. Sometimes, when we have anough awareness, they may help in getting lucid, or they comfirm lucidity. But sometimes we just do them, and they don't result in lucidity. It definitelly is a good sign. If you can, add some more awareness practice and when you examine your surroundings and you RC, believe, that you could be dreaming at that moment.

Btw, did you notice above, that you had a LD?
