Emergency contraception can be taken as a single pill treatment or in two doses. A single dose treatment works as well as two doses and does not have more side effects. It works by stopping the ovaries from releasing an egg or keeping the sperm from joining with the egg. For the best chances for it to work, take the pill as soon as possible after unprotected sex. It should be taken within 72 hours after having unprotected sex.
A single-pill dose or two-pill dose of emergency contraception is available over-the-counter (OTC) for women ages 17 and older.
Emergency contraception may stop ovulation, fertilisation of an egg, or a fertilised egg from implanting in the uterus (womb). Medical research and legal judgement are quite clear that emergency contraception prevents pregnancy and is not abortion.
Abortion can only take place after a fertilised egg has implanted in the uterus.
It is unlikely that you will be pregnant but do a pregnancy test to make sure you are not pregnant if:
- you feel pregnant
- you have not had a normal period within three weeks of taking Levonelle, ellaOne or having the emergency IUD inserted
- you do not have a bleed when you have the seven day break from using the combined pill, contraceptive patch or the contraceptive vaginal ring, or when you take the placebo tablets with EveryDay combined pills.
- A pregnancy test will be accurate if the test is done three weeks after the last time you had unprotected sex.
