Answer 1

I really hope you only want to know for frame of reference -

According to the March of Dimes

Miscarriage

A miscarriage can be an intensely sad and frightening experience. A pregnancy that had seemed normal suddenly ends, leaving expectant parents devastated. About 15 percent of recognized pregnancies end this way.1

Miscarriage is pregnancy loss that occurs before 20 weeks, before the fetus is able to survive outside the womb. Most miscarriages occur in the first trimester or 12 weeks of pregnancy. As many as 50 percent of all pregnancies may end in miscarriage, because many losses occur before a woman realizes she is pregnant.2

Why do miscarriages occur?
The causes of miscarriage are not thoroughly understood. When a woman has a first-trimester miscarriage, her health care provider often cannot determine the cause. However, most miscarriages occur when a pregnancy is not developing normally. Usually, there is nothing a woman or her provider can do to prevent it.

Among factors known to cause first-trimester miscarriages, the most common is a chromosomal abnormality in the fetus. Chromosomes are the tiny thread-like structures in each cell that carry our genes, which dictate all traits from eye color to the workings of our internal organs. Each person has 23 pairs of chromosomes, or 46 in all, with one chromosome per pair coming from the mother and one from the father. Up to 70 percent of first-trimester miscarriages are caused by chromosomal abnormalities in the fetus.3
