4 things to do after unprotected sex

4 things to do after unprotected sex

If you've had sex without protection or a condom broke or slipped off, there are steps you can take to protect your sexual health. Depending on your situation, you may want to consider emergency contraception, STI testing or a pregnancy test. 

Some options are time-sensitive, so knowing when to act can help you make informed decisions. Here are four things to do after unprotected sex and where to find sexual health resources at CU Boulder. 

1. Consider emergency contraception 

If you've had vaginal sex without a condom or another form of birth control, emergency contraception can help prevent pregnancy. Different options are available depending on how much time has passed since you had sex. 

Emergency contraception does not cause an abortion. 

Ella 

Ella is a prescription emergency contraceptive pill that can prevent pregnancy up to five days after unprotected sex. It is generally more effective than other morning-after pills, such as Plan B. 

  • When to take it: As soon as possible, within five days (120 hours). 
  • Weight considerations: Ella may be less effective for people who weigh 195 pounds or more. 
  • Prescription: Required. 

Plan B and other levonorgestrel pills 

Plan B and other levonorgestrel emergency contraceptive pills can lower the chances of pregnancy by 75–89%. These pills can be taken up to five days after unprotected sex, but they become less effective over time. 

  • When to take it: As soon as possible, ideally within three days (72 hours), but up to five days (120 hours). 
  • Weight considerations: These pills may be less effective for people who weigh 165 pounds or more. 
  • Prescription: Not required. 

Intrauterine devices (IUDs) 

Copper IUDs are another option for emergency contraception when inserted within five days (120 hours) of unprotected sex. They are more than 99% effective at preventing pregnancy and can provide ongoing birth control for up to 12 years. 

Copper IUDs may be a good option for people who are concerned about the effectiveness of emergency contraceptive pills based on their weight. 

Where to get emergency contraception at CU Boulder 

The Sexual and Reproductive Health team at Wardenburg Health Center can help you explore emergency contraception options, including prescriptions and copper IUDs. 

Plan B is also available without a prescription for $25 at the Apothecary Pharmacy in Wardenburg and at other local pharmacies. 

Many insurance plans cover emergency contraception, although coverage may vary. If you're on someone else's insurance plan, they may receive an explanation of benefits showing the purchase. 

2. Get tested for sexually transmitted infections (STIs) 

STIs can spread through vaginal, oral or anal sex, genital contact and sexual fluids. STIs can be caused by bacteria, viruses or parasites, and some infections may not cause noticeable symptoms. 

If you're experiencing symptoms, such as unusual discharge, itching, burning, pain or skin changes, schedule a medical appointment as soon as possible. 

If you're not experiencing symptoms but think you may have been exposed to an STI, contact a healthcare provider to discuss testing. They can help you determine which tests you may need and when to take them. 

If you test positive for an STI, Medical Services can help you understand your results, explore treatment options and access additional support through behavioral health services. 

The Sexual and Reproductive Health team can also provide information about preventive medications and vaccinations that help reduce the risk of certain STIs.

3. Take a pregnancy test 

If you're concerned about pregnancy after unprotected sex, taking a pregnancy test can help you understand your next steps. 

When should you take a pregnancy test? 

The accuracy of a pregnancy test depends on when you take it. Some at-home tests can detect pregnancy hormones within 10 days of sex, but results are generally most accurate after you've missed your period. 

When using an at-home pregnancy test, check the expiration date and follow the instructions on the package. 

Where to get a pregnancy test at CU Boulder 

Students can access pregnancy tests through several campus resources: 

  • Medical Services: Schedule an appointment for a pregnancy test at Wardenburg Health Center. 

Free supplies may be limited. Pregnancy tests are also available at most pharmacies and supermarkets. 

Support for an unexpected pregnancy 

Finding out you're pregnant when you weren't expecting it can bring up a range of emotions and questions. Talking with a trusted friend, family member, partner, healthcare provider or counselor can help you explore your options. 

Medical Services provides accurate, nonjudgmental information about pregnancy options and can help you make informed decisions. Behavioral health specialists are also available to provide support throughout the decision-making and appointment process. 

4. Plan for safer sex in the future 

Taking time to explore your sexual health options can help you feel more prepared and confident in future situations. Here are a few ways to get started. 

Explore condoms, barriers and birth control options 

Using barriers during sex and foreplay can help reduce the risk of STIs. Options include external condoms, internal condoms and dental dams for oral sex. 

Check expiration dates and packaging before using barriers. Personal lubricant can also reduce friction and the risk of tearing sensitive tissues during sex. 

Students can access free safer sex supplies at the Sexual and Reproductive Health office in Wardenburg, campus Wellness Suites and the wellness vending machine at the Village Center. 

Students living on campus can also order a free Buff Box with condoms, lubricant, dental dams, finger cots and information about safer sex and communicating with partners. 

If you're interested in birth control, Medical Services offers consultations to help you explore short- and long-term options, potential side effects and how different methods work. You can also visit Bedsider to learn more about birth control options online. 

Keep emergency contraception available 

Having emergency contraception on hand can help you act quickly if a condom breaks or another form of protection fails. 

You can purchase emergency contraception or request a prescription ahead of time. Remember to check the expiration date before using it. 

Make STI testing part of your health routine 

Regular STI testing can help you protect your health and the health of your partners. 

Consider getting tested at least once a year and before having oral, vaginal or anal sex with a new partner. You can also discuss your testing history and results with your partners. 

A sexual and reproductive health provider can help you determine how often to get tested based on your individual needs. 

Ask about preventive medications and vaccines 

Certain vaccines and medications can help reduce the risk of STIs. 

Vaccines are available for human papillomavirus (HPV) and hepatitis B, and preventive medications include: 

  • HIV PrEP: Medication that helps prevent HIV infection. 
  • DoxyPEP: Medication that can help reduce the risk of certain bacterial STIs, including syphilis and gonorrhea. 

The Sexual and Reproductive Health team can help you learn more about these options and determine what may be appropriate for you. 


Sexual assault support and resources 

Sexual assault includes unwanted sexual contact or activity that someone did not or could not consent to. This includes situations where a partner does not use a condom after you agreed to have sex with one, sometimes called "stealthing." 

If you've experienced unwanted sexual contact, support and resources are available at CU Boulder.
