It's too early to really know what will happen with the smaller sac. Some women experience Vanishing Twin Syndrome. It could also be that the angle was wrong, the measurements hard to get (depending on many factors). Or it could just mean that egg was conceived and implanted a couple days later than the first.
At this point, I wouldn't worry about it. The most important thing will be to see if there is growth at your next sono.
