Thanks for query,
It seems that you might have Bacterial Vaginosis
Along with good bacteria there are bad bacteria in the vagina.
When predominance of bad bacteria is there B.V. occurs.
Keep proper local hygiene.
,Iron to keep resistance high.
If routine anti biotic and anti fungal medicines do not work then go for vaginal swab test for sensitivity test.
After report go for specific treatment.
ok and bye.
