Weird symptoms

So I’m 7weeks exactly and all I keep reading is people being sick etc , I do have nausea on and off but all I want to do is eat. I keep wanting rolls and chips with lots of salt and vinegar , or paninis or wraps 🙈🤦🏽‍♀️ does anyone else just want to eat all day long. Only other symptoms I have are sore boobs and tired ... should I be worried
