Why is everything very slow suddenly?

First of all I'm not new to selling, I've done this for many years. I sell on average 5 items everyday but the last 8 days have been slower than ever before. I made 4 sales in 8 days and only received 3 questions from buyers. December and January were good in terms of sales so I don't know what changed suddenly? Has there been a significant change I missed?

I sell clothes and these months are in between seasons so that may be a reason but I checked my 2025 sales and this period was quite good for me last year.
