Does hormonal coil (IUS) cause thrush?

After being on and off oral contraceptives (most of the time cyproterone acetate 2.00 mg and ethinylestradiol tablets 35 mcg) I found moving to a hormonal IUD to be a total game-changer. Positives: Predominantly for my moods and the feeling of being in tune with my body (less water retention etc.). Although my hormonal prone acne got worse for a period of time (2-3 months), this eventually came right. I also lost the positive anti-androgen effects that I was on the pill for. I would say the improvement in mood was so significant for this alone it was worth switching the IUD. Other benefits; not having to think about the pill every day and going from heavy bleeding to light and then non-existent bleeding. Negatives: After nearly 1 year and a half of having the IUD I had a recurring UTI and several courses of antibiotics. I developed lower abdominal pain, bloating, pain after sex and thrush. This would come and go. Results only came back with BV. My gynaecologist suggested a course of Uro-Vaxom (3 months). This didn't resolve my symptoms so I suggested I would like to remove the IUD to see if it would help getting my periods back to rebalance my vaginal microbiome. After removing the IUD and two menstrual cycles later, all my symptoms were gone. I would still highly recommend this contraception - I had zero problems and only benefits up until the UTI and antibiotics.

Getting the kyleena coil inserted was quite painful. I got very intense cramps the moment it was inserted and I felt quite light-headed and a bit sick. The cramping lessened a bit after 5 mins or so but continued for the next few days. I bled for a few days after insertion but it wasn't heavy or anything. Positives: My periods became super light. I barely needed to use any period products - I would just wear period pants for the first 2 days then use nothing. Negatives: Cramping leading up to my period got worse. I got quite bad breast tenderness - a symptom I'd never had prior to the coil. I seemed to get thrush more frequently than before and also had a lot of vaginal dryness. The main negative for me was that I would start getting extremely anxious 1-2 weeks before my period was due. I'd regularly break down crying, read too much into things that people said, be very self-conscious, constantly worry about everything and not want to go out to any social events. I had never experienced anything this extreme before getting the coil. The doctor told me these feelings didn't have anything to do with the coil (she did say there's a small chance it amplified feelings that were already there. I chose to take the coil out anyway just to see, for my own peace of mind. It's like night and day. I got the coil out while I was on my period and the weeks leading up to my next period I did not experience any of these symptoms, and this has continued to be the case since I got the coil out 7 months ago.

I got the Mirena coil fitted back in august before this I was natural and not on any form of contraception for a long time. Since I’ve had the coil fitted I’ve had constant BV (bacterial vaginosis) even the antibiotics isn’t working now, I know it’s from the coil as I didn’t have any issues until this has been fitted. I am sick of it and I’m in quite a lot of discomfort because of the infection that I’ve had for weeks, I have booked in to get this removed. After doing some further research I found that you’re at risk of getting bv when you have the hormonal coil so I guess I’m just one of the unlucky ones.
