I'm hurting and not sure why

So the very top of my belly is really hurting today. My husband says it looked like I grew more overnight, so I'm not sure if it's just from stretching or what. It has been hard as a rock all day. My right flank (back) hurts really bad too. I'm only 34 weeks and don't remember being this uncomfortable with my other 2 pregnancies. Anyone else experiencing this??

I'd say the back thing could be a kidney thing or a gallbladder thing if you have your gallbladder, or just a baby pressing on your organs thing. The top of the belly could just be a stretching thing. You'd figure after 2 you'd already be stretched out but with my 4th one by the end of the pregnancy, it was sure sore at the top. Take it easy for a few days, see if it goes away or call your doc. Hope you feel better!
