I have been told I have a yeast infection. I was given one dosage of Diflucan on Wednesday(herb advice needed)?

I am using probiotics as well. I was on a support site for candida and with my symptoms I am told I have "mild candida". Well I took the prescription Wednesday and not seeing much improvement as far as the burning and itching. Through some search I found it can take up to a week (ugh) to see improvements (is that true?) My real question is can I have this Diflucan and use probiotics while introducing Oil of Oregano. Does the OoO cancel the other two out? Will monistat help? Need relief? My gut wants to just OoO along with that single dose of Diflucan but... wondering if I should lay the pprobiotics aside while I do? or is it worthwhile to do all three? Need relief and any suggestions that have tried and worked.
