Am I just Freaking Out?

So today at work I noticed my back was hurting, and I haven't had back pain yet. Also noticed my uterus felt weird. Weirder than usual, I guess. It felt like someone took an air pump and pumped it up to the max!!!!! I'm 9 weeks and 2 days, could this be the start of a miscarriage? I have no bleeding and no horrendous cramping.
