I have clear discharge like coming out that smells weird, had unprotected sex.

Possible infection: Any time a person has unprotected sex there is the possibility of contracting a sexually transmitted disease or becoming pregnant. That is why it's called "unprotected." Please see you doctor to make sure you do not have a potentially serious infection and if you miss a period, check to be sure you are not pregnant.

Various reasons: Vaginal discharge requires an examination to determine the cause and treatment. Bacterial vaginosis is the most common cause and often has a vaginal odor. Vaginal itching can be a sign of a yeast infection. Sometimes vaginal discharge can be a sign of a sexual transmitted infection. Testing is important to determine the treatment and keep you and your partner safe. Start birth control!
