Gastroschisis in one twin?

Johanna • 18 UCSC student and soon to be gastroschisis mom waiting for my boy/girl twins to arrive💕
At my 12 Week appointment today I found out 1) that we are probably going to have 2 baby girls and 2) baby a has gastroschisis (her insides are on her outsides) the specialist I saw says its not all too uncommon and seems confident that she will be okay but as an expecting mom, I'm freaking out, especially with all the risks that come with having twins.
