Sad news at 20 wk ultrasound

Went to our 20 week ultrasound and found out a cyst has grown in our baby's lungs and it has pushed the heart over and could squish both sides of the lungs. It's called CPAM. The mass is large and taking up a lot of space. We are now at high risk and need weekly ultrasounds to monitor the growth. Also if the cyst continues to grow there is a risk of extra fluid called hydrops to develop which is dangerous. I took two steroid shots and we are hoping that will make the cyst decrease in size. It's been a rough and emotional weekend for me and my husband. We are trying to stay positive. Please pray for us.
