I am a nurse and a woman who works on a women's floor at a major hospital. Every decision we make for a woman who is pregnant is based on what is best for the health of BOTH PATIENTS. This is including all stages of gestation including early pregnancy.
I believe the right to choose ends at conception. In most cases, there were plenty of opportunities to make choices up until that point. In the rare occasion that the pregnancy was the result of force, carrying a baby to birth still a "curable" condition and the baby can be offered to someone who will care for it. If the choice gets down to truly being a dangerous pregnancy for the mother, then I will always say "save the mother" but most of the time this is used because the pregnancy is an inconvenience and not a danger. Even then, most mothers pick their babies lives over theirs when asked to choose...and convincing them to make decisions that does otherwise are often difficult.
I have held babies born at 24 weeks. They are every bit as human as babies born at 40 weeks. Before that, they aren't usually viable outside the womb but a few years ago, neither were babies born at 24 weeks.
Pregnancy is a curable medical condition...and it never last longer than approximately nine months.
I have cared for an 18 year old patient who had a medical abortion (done at a proper medical clinic) and she spent several days in ICU and almost died from this "choice". I was in the room when the doctor was discussing the possibility of maybe needing a hysterectomy. She was one month out of high school. Abortions are not "safe" alternatives to pregnancy. Birth control or abstinence is.
