A complication

I had an ultrasound today there's a potential issue with the pregnancy. Good news: baby is measuring perfect for 8 weeks and the heartbeat is good. Bad news: I have a pretty big sub-chorionic hematoma which wasn't there 2 weeks ago and my yolk sac is abnormally large (measuring 8, anything above a 6 is abnormal). However, I'm not bleeding or spotting. My usually very chill RE called me TWICE today (left a voicemail, then called an hour later and spoke to me) to tell me that I may want to get to a maternal fetal medicine doc ASAP. He didn't say anything about the SCH, but says the enlarged yolk sac could be a sign of chromosomal abnormalities. He says it may be nothing, but I may need to get CVS testing to rule out any chromosomal issues. Ugh, not what I was expecting at all. I'm going to be a bundle of nerves until I can see a specialist, I'm going to try and get in ASAP.
