1st trimester level 2 sonogram

Sara • Identical TWINS? what? How'd that happen?
Recently learned we have been blessed with a set of identicals. Don't get me wrong I'm excited but also terrified...though I can only control a small fraction of factors I feel 100% responsible for the health, growth and safety of them. Getting closer to our scheduled level 2 sonogram and thinking about it terrifies me. What should I expect? Will I be able to see them clearly? Any advice from those who have already jumped this hurdle!
