Emergency contraception, often involving levonorgestrel, is a crucial option for preventing unintended pregnancy. But how *does* levonorgestrel work its magic? It's not a one-size-fits-all answer, as its effectiveness depends on where you are in your menstrual cycle.
The primary mechanism is delaying or preventing ovulation. Levonorgestrel works by temporarily stopping the release of an egg from the ovary. If ovulation hasn't occurred yet, the medication effectively blocks the opportunity for fertilization.
However, it's important to understand that levonorgestrel is *not* an abortion pill. It won't work if you're already pregnant. If fertilization has already taken place and the egg has implanted in the uterus, the medication will have no effect.
Think of levonorgestrel as a 'pause' button for your cycle, buying you time to make informed decisions. Remember, it's most effective when taken as soon as possible after unprotected sex. Always consult with a healthcare professional for personalized advice and information.
