I've been on birth control since I was 13 because of excessive bleeding. I just recently switched from the Nuva Ring to a 3 month supply. I was almost done with the last month and getting to my 3rd week I gotten a yeast infection. I know how to get rid of it and all. I'm just scared of having intercourse and giving it to my fiancé. But then again I'm afraid of getting pregnant as we'll. if so can I get pregnant. While on birth control and got a yeast infection.
