Brief Answer:
Recurrent infections need radical treatment.

Detailed Answer:
Hello,
Thanks for trusting us with your health concern.
Having treatment for vaginal discharge multiple times without being relieved of discharge is distressing. Bacterial vaginosis is usually associated with super added fungal infections and if not treated vigorously is notorious for recurrence. A common reason of recurrent infections is simultaneous improper treatment of the partner which keeps on reinfecting the female partner repeatedly.
A vaginal swab culture sensitivity will be helpful in determining the antibiotic which will be most suitable for your infection.
You have to eliminate certain predisposing factors like:

1) Diabetes by doing one blood sugar (PPBS) test.
2) Recent change in sexual partner or having multiple partner, presence of any type STD.
3) Using any contraceptive pill/ Cu-T (IUD), douching or inserting any foreign object.
4) Concurrent practice of vaginal and anal intercourse in alternate way during same session.
5) Other co-existence factors- irregular diet habit, psychological factor, hormonal imbalance, non-maintenance of genital hygiene during period, cervicitis/ atrophic vaginitis etc.

It may be aggravated by using chemical substance like lubricant/ jelly with condom or soap/ detergent/ other bath products, causing repeated friction & irritation inside vagina.

In this scenario, you must consult with a gynecologist regarding this for proper guidance through pelvic examination (with or without speculum), relevant investigation (like STD profile, vaginal swab test, complete hormone assay etc). Take suggestive measures with supportive medication accordingly.

Please feel free to discuss further. I will be glad to answer the follow up queries that you have.
Wishing you good health.
Regards.
