Period at cd22, should i be worried?

My period has never come this early before. It’s usually every 30 days or more but lately it has been somewhat irregular.

From Jan to April, cycle is between 31-35.

Then the next period was after 42 days which made me miss May.

And then 41 days after next period came in July.

Aug - Sept was 29 and 30 day cycle.

And now October, period came after 21 days.

I am a bit worried, there’s something wrong with me. Any thoughts please?

Thanks all! xx
