How to Prevent Pregnancy After Sex: A Complete Guide for Young Adults
If you’ve had unprotected sex or your birth control failed, it’s normal to feel worried about the possibility of pregnancy. The good news is that there are safe and effective options that can help reduce the risk of pregnancy but timing is important.

Whether you’re a young man or woman looking for reliable information, this guide explains what works and what doesn’t.
1. Take emergency contraception as Soon as possible: Emergency contraception (often called the “morning-after pill”) is one of the most effective ways to prevent pregnancy after unprotected sex. The sooner it’s taken, the better it works. Depending on the type, it may be effective for up to 3 to 5 days after sex, although effectiveness decreases over time.
Note: Emergency contraception is designed for emergencies and should not replace regular birth control.
2. Consider a copper IUD: A copper intrauterine device (IUD) can be inserted by a healthcare professional within 5 days after unprotected sex. It is the most effective form of emergency contraception and can also provide long-term pregnancy prevention.
3. Avoid relying on home remedies: Many myths claim that drinking salt water, taking certain herbs, douching, or consuming mixtures of natural ingredients can prevent pregnancy after sex. These methods do not work and may even be harmful. There is no scientific evidence that they prevent pregnancy.
4. Know when to take a pregnancy test: If your period is late or you notice early pregnancy symptoms, take a home pregnancy test. For the most accurate results, test after your missed period or at least 21 days after unprotected sex.
5. Think about long-term birth control: If you’re sexually active and don’t want to become pregnant, consider using a reliable birth control method such as: condoms, birth control pills, contraceptive implants, injectable contraceptive and hormonal or copper IUDs.
Condoms have the added benefit of helping protect against sexually transmitted infections (STIs).
Pregnancy prevention is a shared responsibility. Men can support their partners by using condoms correctly, discussing contraception before sex, and helping their partners access emergency contraception if needed.
