Re: Is it common to worry about birth defects?
It's completely normal. I had a few "soft markers" on an ultrasound I had, I got a quad screening, which came back pos. and i had a 1 in 6 chance of Trisomy 18, so I was sent in for a Level II ultrasound, and after finding more markers, I had a CVS done, and it came back positive for Trisomy 18. I'm only 20 years old. So I mean it's ok to worry, but it's so rare that young mothers have birth defects.
