I have the meriana iud.and have had bv 2 times since.recently i had a yeast infection now i have creamy pink discharge and a light fishy smell.

Hormonal changes: Many people take birth control pills for cycle control and hormonal balance in addition to contraception. When an iud is placed, people stop taking the pills and return to the environment of hormone imbalance and irregular bleeding. This can remove the protection against BV that the pills offered. This is especially true in heavier women.
