My girlfriend was having a dark-yellow (almost brown), scentless, vaginal discharge. Minor itching was present as well. The stains were clearly visible in her underwear after a day. I had no symptoms of STDs.
Since we live in a place with no reliable doctors (they actually don't care and would just stuff her with tons of varied antibiotics for an overkill), and I'm far more schooled than her, I had to decide the treatment myself.
By her symptoms, I assumed it was Bacterial Vaginosis, so I bought a pack of 500mg Metronidazole pills, we took it together twice a day (so, 1000mg a day) for a week.
In the beginning the treatment seemed very effective, she was using a vaginal pad so we could keep track of the discharges' color and amount. By he 4th day the pad was almost completely white, so I thought she was already ok, but we still kept the pills until the week was complete. We didn't stop having intercourse during this treatment (just a reminder, I was on the pills too).
But, as soon as that week was over and we stopped taking the pills, she started to have the discharges again. Far less than the amount she had before, but each day it increases a bit, and I'm thinking that it will eventually be as much as before.
Any advice on this? Thanks.
