After Short Usage Of Antibiotics, I Have Got A Systematic

After short usage of antibiotics, i have got a systematic candida. For my penile yeast i am using Nystatin, but it looks like it doesn't help, also i used Canesten. I am taking probiotics, echinacea too, to boost my imune system, while i am making a pause of oregano oil. I read oregano oil could be applied right on infection, if it's diluted with olive oil, one drop in teaspon of olive oil. Is it possible to heal my infection that way, and how should healing process looks like?

Thank you! :-)
