Some miscarriages, probably the majority, happen through no fault of the woman who's pregnant, and it can happen even before she realizes she's pregnant. If something is wrong with the embryo or it doesn't implant properly in the uterus, miscarriage will occur early in the pregnancy. Later-term miscarriages can happen because of severe injury. Smoking and diseases such as lupus and insufficiently controlled diabetes can increase the risk of miscarriage. Go to medicinenet.com and do a search on the subject. There's lot of information about what causes miscarriage and what doesn't.

Miscarriages are not usually due to anything the mother did wrong. Certain nutritional deficiencies, a thyroid dysfunction, a hormone imbalance and many other illnesses can cause a miscarriage. For more information, see the article listed above by KimKay. Take care.
