Posting issue

Is there a reason why every 7th video I post just does not get any views at all?

The 6 videos that I’ll post before it will all 99% of the time get 10k views or more but the 7th video I post will get maximum 20-30 views but then the post after that immediately goes back up to a few thousand views. Why does this happen and is there a way I can stop it?
