Not sure what's going on and I need your help!

my first pregnancy, I had NO symptoms. I was a month along before I started to miscarry. I'm CD16, this is my secind cycle and over the weekend I experienced cramping which I'm pretty sure I never get and a feeling of my uterus burning. I normally don't get actual hiccups, like maybe one or two really loud ones and that'd be it, but the other day I got actual ones that lasted for quite some time and today, I feel queezy and exhausted with no motivation. Any thoughts?
