To view your Published and Live Campaigns, click the Home button in the top-left corner of the browser, and then click Campaigns. 
Then click on the Live tab. You will be presented with a list of your Live Campaigns.
Once you’ve published a campaign, it is locked in with Facebook. If you desire to make changes to a published Campaign, you can create a copy of the campaign, then edit the copy. Further, you can stop the existing Campaign from showing more advertisements by deleting it.
