It is not the head gasket.

It should be the valve cover gasket. Nothing serious but better to replace it as soon as you can to prevent further leak.

You should be able to drive till the next oil change since your service interval is at 5000 km.

Valve cover gasket leak is nothing major but is good to fix it to prevent minor engine oil leaks. After replacing the gasket, you should also clean the engine so that you can monitor whether there are any other leakages.
