Sexually Transmitted Infections (STIs) can make you very sick. They can damage your health permanently. You can get STDs and STIs from vaginal, oral, and anal sex.
If you have an STI, you could give it to your sexual partner(s), and you could give it to your baby if you give birth. Having an STI while you are pregnant can cause serious problems for the baby. If you think you have been exposed to an STI, you should get tested right away, especially if you may be pregnant.
