I had my 28 week checkup yesterday, even though I am officially 28 weeks today. Everything looks good. I've gained 10 lbs less so far than at this stage of pregnancy the first time, so that is good. I am measuring at least 1 week ahead, so no surprise that it will be another big boy.
Here is a video taken this evening at exactly 28 weeks. The baby usually has his butt sticking out just to the left of my belly button, which you can see him sticking it out and stretching in this video :-)
