Tired all the time and occasionally sick

Shelbie
I see my OBGYN tomorrow, but I have just been extremely tired and some days sick to my stomach when it comes to food. I either sit around and over eat or can't even stomach the thought of food. I'm a school teacher and have been on break for two weeks now (we go back Tuesday) and i don't know if it's because I'm off my routine or I'm freaking myself out. It's my first and I'm 6 weeks. I was reading earlier today that some women are getting sick from their prenatal. I take the gummy kind. I was doing really good the first couple days after I found out with drinking lots of water and eating just what I was hungry for but not I eat then regret. Any advice?
