Baby Movement

So up until the ultrasound on Tuesday I hadn't felt the baby move. I mean nothing that I could for sure say "oh that's baby". Last week while I was peeing (with a really really full bladder) I could have sworn it shifted from one side of the uterus to the other, but maybe it was just my bladder deflating? But ever since the ultrasound I can definitely feel it move. I think BG (this is it's new nickname which stemmed from Chris's referral to sex determination "boy or girl") was pissed about all the noise we subjected it to during the ultrasound b/c it was jumping and moving all over the place on Tuesday night. I even had trouble falling asleep b/c no position was comfortable with a jumping bean inside. Continued Wednesday morning with random twinges all over the place (high low, front, back... like it was swimming laps). Today it's much calmer, but still noticeable. Even though I've been getting ultrasounds at every appointment, the movement finally makes me feel that a little person is growing inside me not just random pains and pulls and a giant tummy.
