A member asked:
Why does emergency contraception have to be taken within 72 hours? what causes it to be less effective after this time period?

Ovulation: Sperm lives for about 72 hours, and if you have sperm in you when you ovulate (egg released from the ovary), then you will get pregnant. Emergency contraception stops you from ovulating. If you take it after ovulation, you will probably still get pregnant. See your doctor about a reliable form of contraception, and use condoms every time.

Prevents ovulation: Ella (ulipristal acetate) works up to 5 days after sex . Other options best asap but up to 3 days. They work by preventing ovulation, and are not perfect. Regular ongoing birth control works better. Pills, patches, ring are options, but require regular use. Consider long acting options of iud and implant. They're the most effective and easy!
