Chlamydia
Chlamydia is the most common bacterial STD (sexually transmitted disease) in the United States. It is treatable with antibiotics, but if left untreated, it can cause serious issues, including pelvic inflammatory disease.
Chlamydia often has minimal or no symptoms. If symptoms do occur, they can include: abnormal vaginal or penile discharge, burning with urination, abdominal or pelvic pain, and more. Because chlamydia often does not show symptoms, the best way to know if you have it is to test for it. Furthermore, chlamydia symptoms can be similar to symptoms of other STDs, so you may want to consider the Comprehensive STD Panel- this includes testing for chlamydia, gonorrhea, herpes, syphilis, HIV, hepatitis B, and hepatitis C.
