Weird question about miscarriages and chromosomal abnormalities...?

No, its just on a "whim" so to speak. I have 2 healthy kids, and I am currently 35 weeks and 3 days pregnant with #3. He has a chromosome abnormality. The genetic counselor explained that its like rolling dice.....so the answer to your question is no. my husband and I have a healthy 6 year old girl, and healthy 2 year old boy. I did spot at the beginning of my pregnancy with this one, I guess my body was trying to miscarry...but my son is strong and he is still hangin in there :)
