loss of appetite

Na
So I am now 7 weeks prego and I have just about lost my appetite for all foods, even my favorites.. EXCEPT fast food 🙄 
The sight, thought and smell of food turns my stomach. In the very beginning of the pregnancy I was able to eat anything. I was eating very healthy, plenty of fruit and veggies and now I can't even stomach an apple. I haven't vomited yet but I'm nauseous 24/7. 😷 just curious to see how common these side effects are. I've also been extremely fatigued and forever tired. 
All I want to do is lay in bed all day erydayy 😏
