My impressions dropped to 0 on February 4th? And no idea why

Hello, I launched my website at the end of November 2024. Since then my impressions have been growing smoothly, I was doing a good job. I have good content, all the technical aspects are right, I´m starting to post one or two posts a week, and nothing is with AI (I mean I use AI to help me but not something that is fully created by AI and makes no sense). The website is small at the moment 15 urls. Since I launched it my impressions have been growing every week: 100 impressions/day, 250 per day, ... until 500 and everything has gone smoothly nor crazy growth on a day, super organic. Suddenly on February 3, I had a drop and on February 4 went to 0, and it's been there for a week. On Thursday had 5 impressions, and on Friday 2... Anyone has experienced this? I have checked my sitemaps, robots, pages still indexed, I don't have anything spammy... Any ideas on how to fix it?
