What Are My Chances Of Getting Pregnant With PCOS?

I was told i had pcos some years ago. Doctors have been giving me pills like Yasmin and ither contraceptives but i decided not to take them because i am afraid of the effects they may make to my conceiving journey. What are my chances of getting pregnant? Should i take the contraceptives? I am getting narried next year and this pcos worries me so much. What am i supposed to do now?
