First, There are some OTC products with enzymes to attack the Candida, (which is just a crazy amount of yeast build up most likely from high cheap carb intake and maybe some estrogen build up). Look up the company Renew Life. Just one off the top of my head.
Second, do not fear your Doc. His job is to help you out, not to turn you in. There are physician/patient privacy laws that would inhibit him to speak about your issue once he leaves the room with you. Worst thing he will do is just give ya the ol' lecture of how bad taking hormones that are not prescribed to you are, then he'll tell you what to do to stop this or help you.
Either way, see what he has to say first, but most likely you will just need to do a body cleanser type deal. But of course, if the condition does worsen, contact him immediately.
