Many STDs have no symptoms, so get tested to be certain you do - not have an STD. If you are having sex, getting tested is one of the most important actions you can take to protect your health. Find out which STD tests CDC recommends and remember, pregnancy does not protect against STDs. If you are having sex, you are still at risk. If you are not comfortable talking with your regular health care provider about STDs, find a clinic near you that provides confidential and free or low-cost testing.
