Not feeling pregnant anymore

I'm 5 weeks pregnant. I started feeling very tired, cramping, sore breasts, and minor waves on nausea from time to time in my 4th week. Now the last 2 to 3 days I haven't really felt pregnant. I even noticed I'm barely passing any discharge. My breast are only slightly tender, and the cramping is rare. I havent had any bleeding at all. Is this normal?? Im Totally starting to freak out right about now!
