Whats the main cause for a miscarriage?

My doctor said 95% of the time, miscarriages are due to chromosomal abnormalities from either the sperm or the egg. I unfortunately was in the 5%, where the fetus was normal—turns out I have two blood clotting disorders. They only tested me after having a second miscarriage.

Ya I lost my baby at 10 weeks turns out she had Down's syndrome. I assume that's the cause, chromosome abnormality.

Yes. It’s usually a problem with the genetics of the embryo. Something went wrong when the cells started dividing so the baby could grow.

wow thats interesting

I heard something about the chromosome not being enough
