Has anyone ever had abdominal/uterine tightness? Its in the area right between my hips where my lower abdomen is. It doesn't hurt..its just like I guess tight and a bit uncomfortable if I try to do crunches, push ups or when I get up and down off the floor/couch/chair or if I do some yoga poses. Just wondering if anyone else has had this.

is there any chance you could be preggy? If not, I'm not sure what it could be...

No, no chance. I finally went and got checked by a doctor and it was a puld abdominal muscle I am on orders of not much activity for now.
