Feeling like the worst mother

I’m 15 weeks and 3 days and I was at work today but it just got extremely busy where I couldn’t even sit, I was up and running around and I remember feeling hungry but not being able to stop because it was so busy. And when I finally got off, I had half of a sandwich and then had to run errands and haven’t ate since 3 and it was only a half sandwich. Now I’m feeling very terrible because my poor baby must be so hungry...
