Third trimester or late term abortions are not legal in a number of states except in certain medical situations. The time frame referred to as late term is often based on when a baby is considered “viable” (able to survive outside the womb). However, the point of “viability” is a grey area in many medical communities. Most medical communities establish 24 weeks gestation, the later part of the second trimester, as the earliest time of viability. Therefore, the availability of any procedure used in the third trimester is based on the laws of that state.
The abortion issue is one that it seems like both sides are correct, but nobody is ever right. From the pro-life point of view, any abortion is killing a baby. From the pro-choice side, it's a woman's right to choose. It all comes down to compromise, and making the most amount of people happy. I tend to agree that means a fairly early cutoff point, with exceptions for extenuating circumstances. Three months seems as good a time as any.
A woman should have the absolute right to abort her pregnancy right up until the moment of birth. It's her body! Even if she's 9 months pregnant, giving birth, and the thing is halfway out, she should still be allowed to terminate it. In that case, the doctor should quickly confirm her wishes and immediately terminate the pregnancy.
Some women do not realize they are pregnant until beyond their third month of pregnancy. These women should not be punished by a three month cutoff. Furthermore, very few fetuses are able to survive outside the womb before the five month mark. If a pregnancy is still at a point at which the likelihood of fetus surival is still far less than that of death, abortion should still be legal.
There is no such thing as a point in a pregnancy where a woman loses her right to autonomy. Abortion needs to be available to women whenever they need it so as to avoid physical and psychological health problems. The right to terminate a pregnancy lies with a woman as her body is her domain and she is therefore entitled to protect herself however she sees fit.
No absolute restriction on abortion should exist at the point of the third month of a pregnancy. At this juncture, the decision to terminate a pregnancy should be left to the pregnant woman. At the end of the third trimester, the fetus is not yet viable, capable of life outside the womb.
