Based on your description there os no doubt you suffer from an infection, but what type of infection? Thisbis still unclear. And please note that each infection has a specific treatment regimen, so experiementing will not help. If these edications were self-prescribed I would seriously advise against it.
The best thing now would be to visit a doctor snd get yourself examined. A vaginal swab culture and urine culture and sensitivity examination will provide information on the exact condition causing your symptoms as well as the most suitable medication to treatment it. A whitish discharge can be linked to many conditions like bacterial vaginosis
, fungal infection
, etc. Which is why I advise you to schedule and appointment with your doctor at the earliest.
Hope this helps.
