Emergency contraception can prevent pregnancy after unprotected sex or if the contraception you have used has failed – for example, a condom has split or you have missed a pill.
There are 2 types of emergency contraception:
1. the emergency pill – Levonelle or ellaOne
2. the intrauterine device (IUD or coil).
Levonelle contains levonorgestrel, a synthetic progesterone produced by the ovaries, which stop or delay ovulation. Levonelle has to be taken within 72 hours (3 days) of sex to prevent pregnancy. It doesn’t interfere with your regular method of contraception.
ellaOne contains ulipristal acetate, which anti progestin, which also works by stopping or delaying ovulation. ellaOne has to be taken within 120 hours (5 days) of sex to prevent pregnancy.
There are no long serious side effects of using emergency contraception but can cause headaches, tummy pain, changes to your next period – it can be earlier. Emergency contraception doesn’t cause an abortion. They aren’t intended to be used as a regular form of contraception. But you can use emergency contraception more than once in a menstrual cycle if you need to.
