Wikipedia:Did you know/After nominating

Objections to your nomination
A1 : Hooks are subject without notice to copyediting as they move to the Main Page. The nature of the DYK process makes it impractical to consult users over every such edit. Also, watch your nomination's subpage to ensure that no issues have been raised about your hook, because if you do not respond to issues raised your hook may not be featured at all.

Patience
A2 : If there is no response, please bear with us: we won't reject the hook unless someone has raised an unsatisfied objection, even if it has reached the Template talk:Did you know section, according to this. Or if the hook has been approved, we are especially unlikely to delete the hook until it goes on to a preparation area for the Main Page. Other hooks listed in the same section as your hook are also waiting, and scrolling to the bottom of the page gives you an idea of how much longer to wait, as described at Daily headings on the suggestions page.

A3 : If you can't find the hook you submitted on the suggestions page, in most cases it means your article has been approved and is in the queues or preparation areas for display on the Main Page. You can check whether your hook has been moved to the queue by reviewing the queue listings. You can also check the Main Page, and check the archives (where it goes after being on the Main Page).

A4 : If your hook is not in any of the queues or preparation areas, not already on the Main Page, and not in the archives, it has probably been rejected. Nominations can be rejected if the hook is very old and has unresolved issues for which any discussion has gone stale. If you think your hook has been unfairly rejected, you can query its rejection on the discussion page, but as a general rule rejected hooks will only be restored in exceptional circumstances. So be sure to satisfy any objections to your nomination before that happens.
