Good dos and don't books/websites

Hey ladies I'm am pregnant with my first baby😊😊 about 5 weeks along and don't see the dr until Jan 20th. I feel like I hear so much mixed information on what you can and can not do or EAT more importantly and just don't know what to do. Between my family all telling me different things and my husband telling me no to everything (cuz he's an expert lol) my head is spinning. So my questions to you all is there a good place to read up on the dos and don'ts and what you can and can not eat?
