bacterial vaginitis
"I have had bacterial vaginitis unknowingly for two and a half years and my obgyn prescribed me 500mg of metronidazole for seven days. Now I've read alot of comments about how this didn't work or that didn't work and whilst I haven't tried all of these and every woman's body is different. I do know that most couples tend to do "it" more than once a week and I don't know if your obgyn told you this or not but if you have sex unprotected whilst taking metronidazole or flagyl it just gives the BV on him and back in YOU. Which causes the bacteria to just keep getting transferred so if you wanna get rid of it and haven't tried not having g sex then try to not have sex during the 7 days  and 48 hrs after the seven days. It worked for me!"
