20 week scan question

❤️👧🏼👦🏼🤰🏼
Had 20 weeks scan on Friday. Got results back and baby had prominent nuchal fold of 7mm and pelviectasis. Doctor said these are soft markers for trisomy. We had a quad screen done at 15 weeks and it came back negative for all genetic disorders. Anyone have this on their ultrasound and everything turn out ok? Going to see maternal fetal medicine next Friday for a second scan. Doctor didn't seem to worried but just looking for reassurance.
