Whoever came up with the argument that the pill was an abortificent didn’t go further in their research to reading the information packet while not digging deeper into why it says “may prevent implantation.” The big thing is that any hormonal variations in a woman’s cycle may prevent implantations. We know this because we know some women’s luteal phases are too short to allow for implantation and we generally know how the hormones play into the shedding of the uterine lining. However, we did not understand it much further than this.
Current research with the morning after pill (same hormones but at higher dosage for limited time) found that if the pill was taken AFTER ovulation, women got pregnant at the same rate as those not taking it. As such, the first type of morning after pill wasn’t that effective. It worked if taken prior to ovulation and primarily just pushed ovulation back a few days which would decrease the odds of sperm being present in the woman’s system by the time ovulation hit. (NFP people should know sperm can live inside a woman for up to about 5 days. In my embryology class, in rare cases, they’ve been found to survive for seven days. The environment matters as well. Fertile mucus protects sperm and stores sperm in the cervix for a limited period of time)
Now, the more updated version of the morning after pill has an additional chemical which was originally used to attack cancer cells. This directly attacks the cells of the developing embryo and thus I’d say makes the newer version more of an abortificent. SOME versions of the pill now include this chemical as well.
So overall, a woman taking the pill to treat medical problems needs to either do her research or have a good relationship with a doctor who understands that SOME versions of the pill have this other ingredient.
Either way, it’s important to recognize that there is a distinction between taking medication that could harm a child and getting an abortion. A lot of prescription medication for issues not at all related to this can impact fertility (by making unknown miscarriages more likely) or by causing abnormalities and disabilities in a child. The reason pregnant woman are pretty much banned from most medication and can only get access to some medications through their regular doctor is because there’s a lot of weighing out the risks to unborn children. Sometimes you’re increasing or decreasing the risk depending on what you’re treating.
So overall, it’s good for women with regular cycles not to screw with their endocrine system with the pill for the convenience of not getting pregnant. Don’t take medicine just because its convenient. But at the same time, don’t jump to the other extreme and act like the pill is so much more dangerous than other drugs when it’s actually safer than other options in many cases. And sometimes it’s not enough too, but your doctor won’t take you that direction without trying it first. I know women who’ve had menstrual problems so bad that they need blood transfusions on their period and end up being forced into a hysterectomy.
