Is my IUD causing me frequent yeast infections

So for the past year and a half I’ve been experiencing frequent yeast infections. I’ve had ParaGard for the past 5 years and it’s seems that every time I turn around I have BV or a yeast infection or both. I’ve been with my husband for years and he almost always ejaculate inside me and a few days later I have the symptoms like a yeast infection. We’ve both been tested back and forth and I can’t find any relief anyone else with this problem?
