Weight gain during pregnancy

Is anyone else paranoid that they will gain more weight than they should? I’m 15 weeks and have gained 6 pounds. I weigh 126 now. Which is normal I assume. BUT here lately I have not been making the best food Choices. In the morning I eat healthy .. but In the afternoon for dinner I usually am in the mood for something that is not healthy. (Mainly because I’m too tired to cook) And I’m also having to snack on something every couple hours or I get sick. Are y’all making good food choices? What are you doing to stick to healthy eating habits?
