Just about everyone wants to have the power or the ability to turn back the clock and to change circumstances or results to something that is more amendable to what they really desired or didn't want in the first place--sometimes known as a "do-over". When it comes down to first-trimester abortions, the three basic ways of inducing abortion are either via medication, injection, or vacuum aspiration, depending upon the length of time since conception. In regards to medication and injection, these procedures essentially fool the body which consequently results in a medically induced "miscarriage" which will often involve discomfort, bleeding, and the discharging of fetus tissue. However, in most cases no surgical instruments will have been used inside the cervix or uterus of the woman, which means that any possible internal injury will have been averted. On the other hand, for vacuum aspiration, typically a local anesthesia is used on the cervix for the ease and comfort of the insertion of the medical instrument which will essentially vacuum out the fetus from the woman's uterus.
While none of these procedures sound very pleasant and while none of them seem very comfortable, they are, in the end, almost always totally effective in producing the result that is to be expected and typically within a very short period of time, the woman is able to essentially go back to living life as if none of this had ever occurred. For some women, there may be significant psychological issues that bother them from their abortion, for others there may be nothing, and for most there is probably a combination of a multitude of feelings, but none of this will change what has happened, which is in essence, as if the pregnancy never existed, by virtue of the fact that no child was born.
While many may applaud that "pro-choice" is a wonderful modern construct that allows women to take charge of their bodies, one could make a very valid argument instead that the ability to get an abortion "on-demand" with a relatively small monetary cost is an avenue best left unexplored. According to guttmacher.org "in 2011, 1.06 million abortions were performed" in the United States, a statistic that is especially troubling considering that the availability, reliability, and variety of birth control items have never been greater than they are here today. This then begs the question, why would any woman, of any age, willingly put themselves into a position to which they might become pregnant? The obvious answer to that question is that women are obviously quite aware that they can take advantage of the fact that abortion is fairly easily available in much of America and consequently they have a relatively good "fail-safe" method of un-doing what has been done.
Because abortion is legal, readily available, relatively inexpensive, and physically safe, women are allowed to make the same weak decisions or non-decisions over and over again, because apparently the consequences of said decision have been found to be not so bad. If, on the other hand, abortion was a procedure that was either illegal, dangerous, very expensive, or with high social costs, then women really would take charge of their bodies and of their decisions.
