Emergency Contraception can prevent an unplanned pregnancy when no contraception was used, when contraception failed or when contraception was used inappropriately.
Emergency Contraception can prevent an unplanned pregnancy in the following situations:
- No contraception (e.g. condom) was used
- Missed birth control pills, patch, or ring
- Interference between birth control and other medications (e.g. antibiotics)
- The condom slipped, broke, or leaked
- Non-consensual sexual intercourse (sexual assault)
There are 3 options for emergency contraception.
Please read below to see which option may be appropriate for you.
1. Plan B
Plan B is a safe form of emergency contraception that only contains progestin. It is used to prevent pregnancy up to 72 hours (3 days) after a single act of unprotected intercourse, however, there is some evidence that it may be used up to 120 hours (5 days) after unprotected intercourse, but that it may not be as effective. It may not be effective for women who weigh more than 165 pounds. According to Health Canada Plan B is not effective if you are over 176 pounds. Plan B is not intended as a method of birth control; it is for emergency use only.
Ella is a safe form of emergency contraception pill (ECP) that contains the active ingredient ulipristal acetate. It works by blocking the effects of the hormone progesterone. Ella is used to prevent pregnancy up to 120 hours (5 days) after unprotected intercourse. It may be less effective for women who have a Body Mass Index (BMI) over 30kg/m2 or are 194 pounds or more. Ella is not intended as a method of birth control; it is for emergency use only.
3. Cooper IUD
The IUD is a long lasting method of birth control that is inserted into the uterus (womb). It is a T-shaped plastic frame that is surrounded by a thin copper wire. At the bottom of the IUD there is a string. A copper IUD can be used by individuals not wanting to become pregnant up to 5 days after unprotected sex.
