Not feeling good at all

So my last period was September 8-13,I found out I was pregnant October 9, I was completely fine up until the 22nd I just feel so sick, I haven't thrown up but it's like I have lost my appetite so I'm forcing myself to eat, 30 mins to an hour after I eat I feel completely empty and sick as hell, this is my first pregnancy and I have no idea what I'm in for, if anyone knows something I can take to help me feel better please feel free to comment
