If its not an allege then what is it?

Patient: I think im allergic to Trojan condoms because every time I use the green or gold colored condoms I get a discharge. But when I went to my doctor about this probable they told me that im not allergic to them and just tell me that I have a yeast infection. Also when I take the pill for the yeast it does go away, but from my understanding of the pill is that after you take it, it makes it harder for you to get another yeast infection. It cant be my the soap I use because I am very careful about the soap i use on that area.
