Should I kill my current campaign and start over?

Hi everyone, very new to Meta ads so excuse any ignorance. I started a campaign to gain followers (the main objective of my employers) which was majorly successful.

(Six ads in the ad set, some video, some static).

Things started to slow down a bit and some of the ads weren't spending anything or garnering any attention. So I did some research, turned off three ads in the set and created three new ads which I believed would perform better.

Now, the whole campaign seems to have hit a dead end. Our follower count was rising about 100 a day all from ads, and now it's at 0. I'm so confused as even the really successful ads aren't performing well. Is it ad fatigue?

I've waited twelve days for a change. At this stage should I just turn off this campaign and start a new one? I'm dying to see the same results I did at the beginning!

Thanks for your help.
