Feeling helpless

My first US (at 7 weeks) showed baby measuring 5 days behind and an enlarged yolk sac (7mm). I went for a follow-up 2 weeks later and baby was only measuring 3 days behind, and they said the yolk sac was "prominent," but said everything looked good because baby was growing and heartbeat was 161.

Then I had my nuchal translucency scan yesterday. Heartbeat was good at 165, but I was measuring 6 days behind. There was also presence of neck skin edema with septations (consistent with cystic hygroma), and a NT measurement of 4.7mm. I didn't get the blood work that goes with the scan, I opted for the cell free fetal DNA blood work instead and I'm waiting for the results (hopefully by Friday).

I have a CVS and genetic counseling scheduled for next week just in case.

I'm trying to stay positive, but it's really hard. I feel completely different this pregnancy than I did with my first. I didn't really have morning sickness with my first, but I had some nausea, food aversions, and I was super tired. With this pregnancy I don't feel pregnant at all. No nausea, no food aversions, no cravings, no fatigue. I know every pregnancy is different, but I just feel TOO different.

Any thoughts?? I don't really have a support system where we live, and my husband is just as worried as I am. I just want to talk to someone objective. Maybe share similar experiences (good or bad). Thanks for listening.
