hap0206, C'mon, Miscarriage is the sudden loss of a pregnancy before the 20th week. About 10% to 20% of known pregnancies end in miscarriage. But the actual number is likely higher. This is because many miscarriages happen early on, before people realize they're pregnant. The term miscarriage might sound as if something was amiss in the carrying of the pregnancy. This is rarely true. Many miscarriages happen because the unborn baby does not develop properly. https://www.mayoclinic.org/diseases-conditions/pregnancy-loss-miscarriage/symptoms-causes/syc-20354298
On the content below i think it's fair to say miscarriage is as much a medical term as "common cold" is.
"Noticed you called it “miscarriage” — Not — I had an “abortion” Wonder why you let the meds call it “missed abortion” I guess they didn’t know whether you wanted the child— or not"
As far as your "wonder why...." rubbish, see below...
Miscarriage
A miscarriage is the spontaneous loss of a fetus before the 20th week of pregnancy. Pregnancy losses after the 20th week are called stillbirths. Miscarriage is a naturally occurring event, unlike medication abortions or abortion procedures.
A miscarriage may also be called a "spontaneous abortion." Other terms for the early loss of pregnancy include:
* Complete abortion: All of the products (tissue) of conception leave the body. * Incomplete abortion: Only some of the products of conception leave the body. * Inevitable abortion: Symptoms cannot be stopped and a miscarriage will happen. * Infected (septic) abortion: The lining of the uterus and any remaining products of conception become infected. * Missed abortion: The pregnancy has failed and the products of conception do not leave the body.
Your health care provider may also use the term "threatened miscarriage." The symptoms of this condition are abdominal cramps with or without vaginal bleeding. They are a sign that a miscarriage may occur.
Causes
Most miscarriages are caused by chromosome problems that make it impossible for the fetus to develop. In rare cases, these problems are related to the mother's or father's genes.
