Early Ultrasound - Tell Me Your Stories!

I had an early ultrasound yesterday at 5 weeks 3 days. My OB immediately found a sac, measuring 5 weeks 5 days, and then pointed out another possible sac (which could be another baby, could be fluid, could be nothing, etc). It measured 5 weeks 2 days.

She said that we'll be able to see what happens with it at my next appointment (in just over two weeks).

Does this look promising to you? I’m trying not to get my mind set on there being two yet, but I’m curious. Any similar experiences? How did it turn out for you?
