I am pregnant with my 2nd baby and I am 19 weeks along. I just had an ultrasound done last week and the doctor found 2 "markers". One being in the small intestine and one being in the heart. He explained to me that I am now at a high risk of having a down syndrome child, but he could not give me a percentage or any details. I am 28 years old. Has anyone gone through this?? I am depressed and have opted not to have the amnio done. I just need a glimpse of hope.
