Ok, i know that cramps are normal stuff, but can anyone help me out on this one?

Ive got aching muscles, starting at the top of my pubic bone, going down into the tops of my thighs. It hurst when i walk, sit and then get up, roll over at night... basically anytime i move. Its not so bad that i cant do these things, but its annoying as its been about 3-4 days and is not getting better.

Also- what about kidney/sideback pain? Ive been tested for- well i dont know what exactly- the last 2 times i saw the midwife and ob to see if this pain was an infection etc but they come back negative.

Its been ongoing since day 1, i think 2 weeks is the most ive gone with out the kidney/side pain---

sooooooo am i right in assuming that its just everything growing?
