Why did my first 2 videos get 15-25k impressions but my third only got 4?

hello everyone, I started uploading videos to my channel roughly 10 days ago, the first video got around 400 views and 30 likes, and around 24 impressions, my second video got around 400 views with 20 likes, and 16k impressions. Then I ended up getting really sick and didn’t have the strength to make videos. I uploaded my first video, then around 3 days later uploaded my second, but I uploaded my third one around 6 days after my second, and it only has 4 impressions and 1 view. note: my first 2 videos got views pretty quickly, and they together gained my 30 subs. During he period when I was sick I streamed twice in one day for Around 30 minutes to figure out settings and stuff, aswell as to configure my mic as it was buggy, etc, idk if that negatively affected the channel. I just need some help ablut What is going on, I also make sure to put tags and hashtags in the videos. or is this normal for a new channel?
