BV w IUD

Ke
Hey girls ! So ever since I got this IUD Mirena ( which I loooove) I am prone to yeast infections 😩 . & recently I've discovered a funky smell 😳 & I only smell it when I have sex .. last time this happened I had BV & used a cream for 7 days. But do you guys know any other ways to prevent this ? Should I see my OB/GYN ?
