Birth control causing yeast infections

Rubixedee
Hi ladies. 
I have been changing my birth control every 6 months for the past 3 years as I have been having recurrent yeast infections EVERY month. 
I have been using yaz for the past 4 months and I have been having recurring yeast infections every month still. I don't know what to do. I have tried everything to get rid of them, yoghurt insertions, all types of over the counter medications, tea tree oil. I don't take sugar or bread (for over a year). 
I have had sugar tests etc. so I have narrowed down my issue to bcp.  Any suggestions of what pills I could use that could help with this issue?
