Thanks for your question. It sounds as if you have considered some of the possible answers already. In general, the fishy smell can be associated with some of the bacteria that cause or are involved in bacterial vaginosis, or BV for short. That being said, it is not always that the smell is indicative of an active infection, or it could also be that there are different bacterial, viruses, or fungi that are related to your symptoms. Your doctor
will be able to help with this problem, although this will mean making the time to discuss the symptoms with your doctor. It may be possible to relate some of this over the phone, especially if you have been keeping up on your routine physical examinations with your doctor. As your symptoms seem to be quite likely related to some bacteria or change in the flora of your genitalia, and the smell appears to be new since your piercing, it could be related to the piercing itself. The irritation might not be at fault, but the difficulty in cleaning this body part now that there is a new piercing and foreign body can be more difficult. Again, please speak with your doctor.
