Mirena and recurring YI

Hello,

I'm fairly desperate for help. I'll try to keep this long story short.

In june, I started having some burning after sex, lots of yellow stringy CM and a faint odd smell that I thought could be a YI. I took the monistat at home test kit and it said it was likely BV. I went to a family doctor who said that he wanted to save us both the embarrassment of doing a test and said prescribed me diflucan because that's what he thought it was. I took that and it didn't help, instead it just came and went and came back on and off. About a month later I was prescribed another round of diflucan because I couldn't get it to go away. In August when it seemed better but when I got my mirena and that made it all kinds of worse. It was back and I went to another doctor. She tested me for a bunch of STDs and Yi and Bv and it came back as a Yi. She gave me a double dose of diflucan and I started taking an expensive acidophilus and eating less sugar and carbs ect. It came and went and came and went until suddenly it was really bad and I got a this horrible smell that developed. Not like fish but just something awful. Through my jeans I can smell it. I went to my midwife this time and she tested me to Bv and Yi and herpes. It came back as a Yi again. I was told to take monistat so I did. I hasn't helped at all.

It's seemed that since I got my mirena, this issue has gotten all kinds of worse. The smell will drop you dead. It's so embarrassing. So much watery stringy yellow tinged discharge...I've been trying to stay away from people, I'm avoiding sex with my bf because I'm so embarrassed. I've never had this problem ever. I feel like it has to be bv? Or could mirena cause something else? Are recurrent Yi common with mirena?

As a recap, I've done 3 rounds of diflucan, one of monistat, probiotics, acidophilus, oil of oregano capsules, vitamin c, less sugar, less carbs... I just want my vagina back and mirena is my latch ditch birth control option 😭
