I m on Yasmin birth control and had no problems for the first 3 or 4 months. Now I have sore breasts and constant recurring thrush. I have had blood tests to rule out diabetes and have had swabs to rule out any other infection. All results point towards thrush. Could Yasmin be causing this? Should I try changing my pill and if so what should I change it to? P.s. I am 26 and in good health, non smoker
