Morning sickness-advice please :)

Charley
Hi all, I am in need of some advice!
I am 7 weeks 4 days and I started feeling ill on Friday. I threw up once on Friday afternoon and then yesterday (Saturday) I was literally sick all day and threw up five times, I couldn't keep anything down. By the time I went to bed around 11:40pm, I was able to keep down a piece of bread and I slept through the night. 
As for today (Sunday) I still feel super weak, light headed and nauseous. I do have a slight fever but haven't thrown up yet today. 
Up until Friday I had no sickness whatsoever and felt pretty great overall. I am just wondering if this is morning sickness or if I may have the flu? And how long should I wait before contacting my OB/GYNs office? I don't see her until Jan. 17th, so they just told me to call if I need anything before then.
