If you have a sexually transmitted disease (STD), you should always get treatment; however, this is especially important if you are pregnant. Some STDs, such as HIV or herpes, can harm your baby. Ideally, you should be screened for STDs before becoming pregnant, but if you are already pregnant, you should still be tested. Medications can often help manage your STD symptoms during pregnancy and help prevent passing STDs along to your baby.
