Emergency contraceptive pills (ECPs), often called the morning-after pill, can help prevent pregnancy after unprotected sex. However, their effectiveness is highest when taken within 72 hours (3 days) of intercourse, although some can be taken up to 120 hours (5 days) later. The copper IUD is another method that provides immediate protection against pregnancy upon insertion. Note that other forms of birth control, such as the birth control pill or implant, do not offer immediate protection. You can become pregnant immediately after removing an implant.
Methods for Immediate Pregnancy Prevention:
- Emergency Contraceptive Pills (ECPs): These pills are most effective within 72 hours (3 days) but can be taken up to 120 hours (5 days) after unprotected sex. Their effectiveness decreases the longer you wait.
- Copper Intrauterine Device (IUD): This device is inserted into the uterus by a healthcare professional and provides immediate protection against pregnancy. This method prevents pregnancy via spermicidal mechanisms, even up to five days after unprotected intercourse.
Methods That Do Not Provide Immediate Protection:
- Birth Control Implant: While highly effective long-term, pregnancy is possible immediately after removal.
- Other Hormonal Contraceptives (Pill, Patch, Ring, Injection): These methods require consistent use before offering protection.
It is crucial to consult a healthcare professional for advice on contraception and emergency contraception. They can help you choose the method that best suits your needs and discuss any potential risks or side effects. Information on various contraceptive options, including condoms, can be found at Queensland Health's website.
