Anyone else have major back pains?

My back is killing me. Mainly where my love handles are at the bottom of my back and also at the center. It feels like my kidneys are hurting or something. IDK how to explain it. And my stomach is sore to the touch. Its like I ate a huge meal. Is this baby symptoms? I looked online and it said I may just be stopped up and have to poop. I haven't been able to in two days. What do you guys think?
