Cystic Hygroma

Three weeks ago I went for my first prenatal apt and was told everything looked great. Today I went for a second apt with ultrasound which was kind of odd that I had a ultrasound because first two pregnancies I’ve never had two so close together except for in the last few weeks of pregnancy. I was told today that they suspect that Baby has cystic hygroma and that’s why they scheduled a second ultrasound to see if it has shrunk since last apt even though they never said anything about it last time. They are sending me to a specialist to do further testing to see exactly what’s going on. Anyone that has gone through this I would love to hear the outcome. I’ve done research and am kind of paranoid.
