Kidney stone!!

So I've been having this left flank (side) pain for a while now so my OB sent me to have a renal u/s done and come to find out I have a kidney stone. The u/s was no fun at all, I had to drink 32oz of water at 7:30 and hold it until I had the u/s at 9:00. By the time the tech came to get me I thought I was going to pass out. Holding you pee is normally hard but having a baby pushing on your bladder makes it just that much more difficult. So needless to say I am not a happy camper, the horrible problem is I can't do anything about it because I'm pregnant and the good meds are out the door. So I basically have to suffer and hope it passes soon with ease. No fun! After reading about it apparently if you have had any kidney stones in the past you are more likely to have them resurface while pregnant. And more often then not the don't pass until you deliver. So wish me no pain and luck passing it I'll need it! I am 22 weeks 6 days, Kristen the x-ray tech wanted to peek at the baby when I had the renal u/s and she printed me this picture for fun. He was doing breathing exercises and won't stay still for a good picture because my bladder was the size of a watermelon and was taking up his space. He was sucking his fingers at one point. This was the only thing good that came out of the renal u/s.
