Hey, remember that time I wrote about courting? Yeah, I thought so. This post is kinda similar in that I'll be dispelling myths of jean-skirted, Sketcher-loving women who do Natural Family Planning.
First of all, most people don't know what in the world NFP is. Natural Family Planning is a method of avoiding pregnancy that relies on a woman's natural signals and hormone cycles in order to determine when she is and is not fertile. Instead of pumping your body full of hormones, it uses the cycle of hormones already raging in your body to let you know when intimacy is a go and when it's not so much.
In order to really understand NFP you have to have basic knowledge about hormonal cycles, temperature fluctuations, etc. and be willing to track it.
I won't stamp the pill and other hormonal birth control methods with the condemning "it's abortion" stamp, but I will say for me I feel extremely convicted about taking the pill. Knowing how it works both in my own body & in a textbook setting, I think it would be sinful for me to be on the pill, not because the pill is inherently sinful, but because I have heavy convictions about it for myself. If you take the pill and don't feel convicted, live in grace & keep on taking it! If you take the pill or are on other hormone-based contraceptives, know how it works. So many women are totally okay with popping a little pink pill everyday without even reading a pamphlet on what it's doing to their body.
Basically, the pill has 3 methods of working: 1) preventing ovulation, 2) making the female reproductive tract super acidic, 3) thinning the uterine lining. The first method is typically not controversial. Preventing ovulation is a pre-zygotic barrier, meaning it prevents contact between the egg ('cause its not available to be fertilized) and sperm. The second and third methods are however controversial and heavily talked about because they act in a post-zygotic manner, meaning potentially after fertilization has taken place (and thus are considered by some to be abortive).
NFP takes all the guess work out of birth control by using your body's own hormones, rather than artificial ones. NFP celebrates the female body for one of it's God-given, beautiful purposes: to be hospitable to life.
