When I tell people I don’t believe in using artificial birth control, they often think I’m one of three things: a hippie, a nut, or an overly religious, old-fashioned conservative.

I can tell you I’m a religious, old-fashioned, and fairly conservative young woman. But I’m not crazy and I’m not into conspiracy theories.

My husband and I chose to save sex for our wedding night, largely because it’s what we believed was morally, physically, and spiritually right. But we were also scared. Scared of getting caught, scared of getting pregnant, scared of regretting it later. No matter the reason, it was the best decision we could’ve made.

For that reason, I didn’t need to think about birth control until a few years ago. I had irregular cycles and acne as a teenager, but I never wanted to ask for birth control pills to address those things. I didn’t want to give my family the wrong idea, and I didn’t, frankly, want to tempt myself.

As Erik and I matured and began planning our marriage, we did a little more digging into church teachings about family planning. We knew the church taught against artificial birth control, but we didn’t know why. Was it just outdated, like everyone said? Was there an alternative that wasn’t just plain risky? Were we prepared to have a busload of kids?

So we looked into it. When we read that the pill—which seemed like the easiest option—could serve as an abortifacient form of birth control, we decided to do even more research.

So I want to talk about the pill. I don’t think women know enough about it, simply because we’re never taught enough about the way it works. So I hope this is helpful.

In sex ed, everyone tells you the pill works by tricking your body into thinking it’s already pregnant. In fact, people still tell me that if I ask them how it works today. The thing is, it’s not really that simple. It adds hormones to your body in a similar way that a pregnancy would, sure. But that’s not all it does.

Hormonal birth control—i.e., the pill, as well as most patches, IUDs, injections, and other chemical forms—works in four ways:

• Suppressing ovulation to prevent your ovaries from releasing an egg during each cycle
• Altering your cervical mucus so it’s more difficult for sperm to navigate
• Disrupting the way the cilia in your fallopian tubes move to reduce the chances of a fertilized egg reaching the uterus for implantation
• Inhibiting the growth of your uterine lining (the endometrium) so any fertilized egg could not attach properly
• (In some cases, the “mini-Pill” (a progesterin-only option) may not prevent ovulation or conception (those first two tactics) at all.)

Two of those effects are designed to prevent conception. But the last two prevent implantation—meaning your body hasn’t been tricked, knows you’re not pregnant, and has ovulated as it naturally would. Your cervical mucus wasn’t thick enough to keep sperm from traveling through you. So an egg is fertilized, and pregnancy has begun.

The pill doesn’t give up, though. The third effect prevents the body from moving your fertilized egg to the uterus, where implantation would take place and the embryo would receive the nutrients necessary for development. The fourth effect changes the environment of your uterus and prevents that viable zygote from taking its place in your womb and growing. That zygote—though very tiny—has its own DNA. It is individual of the woman’s body, in that her DNA and her partner’s—two human parents—have joined to create a third entity. Science has proven that conception is the moment a new individual (and, therefore, a pregnancy) begins—not implantation. The DNA is human. Given the simple resources a pregnant mother provides (a warm, safe place, nutrition, and oxygen), that individual will grow into an infant who, in just a few months, can be held and tickled and nursed in its mother’s arms.

Occurring about a week later, implantation is simply the end of the embryo’s journey down the fallopian tubes. It settles into the uterus by attaching to the endometrium, which provides the nutrients it needs to grow and develop. That little individual—with new DNA and a separate makeup from its mother—has already existed for several days. When the lining of the uterus has been altered by the pill, the implantation factors of the lining—key chemicals, as well as special molecules known as integrins—are damaged and unable to perform their job. So imagine that zygote is a plane led by a pilot, and the uterine lining is the airport. If the crew at the airport can’t communicate with the pilot flying the plane, the plane can’t find a safe place to land. And if the plane can’t land, the pilot won’t survive long.

The “morning after pill” works this way, too. It’s just a high dose of the hormones that will delay ovulation and/or alter the endometrium, with the hope that ovulation will not occur or, if it already has, that the uterine lining will be compromised before the embryo reaches it. The plain old pill just does it a little slower.

So, anything that works to prevent conception can be called contraceptive. But anything that fails to prevent contraception can’t share the same term. Conception has already happened. At that point, your pill becomes abortifacient. That is the scientific word for anything that stops a pregnancy after conception has already occurred.

That said, even if the birth control industry came out with a pill that didn’t have an abortifacient effect, I still wouldn’t take it. Aside from the health risks (which I’ll also address in another post), I don’t think it empowers women. In fact, it literally—by which I mean physiologically—suppresses the women who take it.

What message are we sending our future daughters when we say that taking the pill—effectively turning off a natural function of our bodies, and altering the way our biology works—is the only way to gain control over our love lives, our families, and our sex lives? That’s the opposite of support. It conceals a woman’s natural, complex biology so she can become an object of pleasure. It’s repression. And I don’t buy it.

Our bodies do amazing things each month. That’s part of our feminine identity—it’s the magic only we can make happen. And it’s not just about the fact that we can carry children. Sadly, some of us can’t. In every case, understanding the way our natural cycles affect our day-to-day wellbeing gives us greater insight into our health and physical selves. It’s about knowing yourself, truly. It’s about taking ownership of the complex, profound woman you were literally made to be. It shouldn’t be about stamping out your nature because you were never taught how to handle it on your own, or that it was worth protecting. We’re capable of so much more than that. All of us.
