Actually, my OB/GYN friend told me that all miscarriages are medically-termed spontaneous abortions (if herein "miscarriage" means the end of a pregnancy without interference from the mother or outside injury/procedure). They're just not often called that to patients and the public because of the emotional investments in the "A" word.

That must be hard on a body, to go through all those, though - emotionally perhaps (not to hurt your feelings, but just to be honest - there are many that occur early enough that a woman might never know it), but I'm thinking physically. You have my sympathies.
