Regardless of your age and financial situation, there are clinics, health departments, and non-profits that can help you. Do not avoid getting tested or treated because you are scared you cannot afford it. Many health departments have free or low cost testing. Even if you are experiencing pain or think something may be wrong, they can write referrals to local OBGYN's. If you are scared of your parents knowing, you can request that all of your information not be shared if you are over 13 years old (in Alabama). Take care of yourself. Part of becoming an adult and having sex, is making sure that you are healthy!
