The alternator normally produces a higher voltage when the engine is first started in order to quickly recharge the battery. The voltage will decrease to a lower level while the battery charges. It's normal for voltages to alternate between higher and lower levels; this cycle is known as the "charging cycle."
In order to avoid overcharging and increase battery life, certain alternators are made to lower their output voltage after the battery is fully charged. As a result, the voltage may then drop to about 12.7 volts.
Now, just to be sure there's nothing wrong with your charging system or alternator, you can have it checked by a qualified mechanic or at a nearby auto shop. To confirm everything is operating as it should, they can test the charging system and verify the output voltage of the alternator. Hope this helps!
