Worrying about how I’m feeling

So I know everyone is sick of reading “Is this normal posts?” because I’ve seen A LOT of those ! But I am a First Time Momma🤰🏼 I do plan on calling my OBGYN to discuss in AM but - I have been have on and off temperatures; the highest being 101.4 ! I had diarrhea for one day and that was it with it. I’m just feeling completely cold 24/7 and I have seemed to have lost my appetite-all I want to eat is fruits and veggies + drink water and Gatorade. Does anyone experience similar things or think this is something serious? :( I am a little over 7 weeks currently.
