How many reels is enough for deciding if my content is working or not?

just started posting 5 days ago. so far I’ve got 21 posts, 9.4K total views, 0 followers(3 being my friends so it doesn’t count).

my content is 3-8s reels of my selfie with captions, with #relatable #fyp #funny #friendship #foryou

Initially the captions are copied from TikTok, then i started to come up with original content. My target audiences are GenZ ppl.

examples:

1. how it feels to text ur hb knowing it will take them 3-5 business days to reply

2. POV: when i wanna talk to someone but forget the word i should use

3. I’m so glad to have u in my life, twin

what problems could you see here?
