Anyone have abnormal result in QUAD test?

Mr

Got the news today. Doing a level 3 ultrasound on 11th of March. I opted for amniocentesis to be last resort. I had one before and didn’t like it. It hurt and I almost miscarried. Pregnancy is with placenta issues, on steroids, no weight gain, high blood pressure and light mucusy bleeding since I was 14 weeks. Currently 18 weeks 5 days.

Anyone have experience with how that level 3 works? Abnormal results with good outcome or even “bad” ? Baby is loved no matter what. Just want to be prepared as possible
