since even my pro choice mom thought plan b was an abortion pill, here’s how it works to *prevent* pregnancy, not terminate: plan b releases a synthetic version of progesterone, a hormone that is released post-ovulation. when there are high levels of progesterone in the body, that makes your body think it’s already ovulated and prevents or delays the release of an egg. it also thickens cervical mucus so it’s more difficult for sperm to reach the uterus.
