I don't know what to do with the pregnancy hunger..

Hello,

I am 7 weeks pregnant. I am hungry every five minutes. My baby doesn't seem to like house food but, loves restaurants food. Today, I wanted rotisserie chicken and my sister got mad at me. Telling me that I need to watch what I eat. I have been watching what I eat. I literally google if certain food is safe to eat and how much can I eat. I also he healthier options as well like fruits and veggies. I just don't know what to eat anymore really. I also feel like my family doesn't really understand where I'm coming from. Just kinda feel alone about this issue. What do you mother's do to satisfy your hunger?
