20 weeks and heart problems with baby a

And totally miserable! The twins are measuring 2 weeks bigger which I'm happy about. We found out we are having girls and decided to name them Elizabeth Adeline and Bridget Genevieve. Elizabeth looks like she has a hole in her heart. We have to go to a pediatric cardiologist next week. We are looking good so far along the lines of TTTS. I'm feeling slight movement but not a lot. I haven't been able to take it easy. I've gained 14 lbs to date but feel like I can't get much bigger than I am now. I'm sooooo uncomfortable!
