Fb ad randomly stopped showing

My FB ad just stopped showing. I was getting some really good traffic but it just came to a sudden stop. It wasn’t due to a budget maximum or the time period that I had set for the ad. I checked everything I could think of. Someone mentioned to me that I may have gotten out-bid. Can someone help me on this.

Hi Abigail,

Can you send a screen shot so we can take a look?
