Today was the hardest day I've had since I've been pregnant... so much pressure in my ribs and pain in my pelvis.. didn't help that I worked about 12 hours on my feet (iPhone launch) had to leave work early because I couldn't stand anymore! I drank about 100 oz of water so I know I'm not dehydrated just worried about my boy. He didn't move much today, but now that I'm laying down he's starting to move around.
