Cystic Hygroma

I am 10 weeks 2 days. Went in for an ultrasound, technician said she easy concerned about edema. Left. Met with doctor, told us baby had cystic hygroma. Heart rate was strong at 188 and baby measured at 10 weeks 6 days. So baby is growing. Does anyone have advice, thoughts, personal experience? I'm so overwhelmed. We are meeting with a genetic counselor Monday. I love this baby and will do anything for it. I just need hope.
