Mirena and oral thrush

I had the Mirena IUD inserted on October 10th. I had it switched from the copper IUD because I was spotting dark brown blood prior to my period, so my gyno recommended the switch. I spotted for the rest of the day, then stopped for two days, then began what I would call my period, since I was due for it later that week anyway. I am still bleeding, but I'd like to believe I'm nearing the end, since it seems to be lightening up. I expected my period to be fairly long after insertion.

The day after insertion, I experienced severe itching and swelling down there, and decided that I must have a yeast infection, but both symptoms are listed as side effects on the sheet I got from my pharmacy. I treated the infection, but still itch from time to time... I'm wondering if it's the hormones in the IUD.

On the weekend of October 19th, I lost my appetite, my sex drive, all sense of sexual pleasure and my ability to acheive orgasm. I ate three meals all weekend long, and only because I felt that I should eat, not because I was hungry. Sexually, I felt friction and not much else. Upon trying to climax 4 seperate times over the course of the weekend, I failed at all 4 attempts and all I got from my efforts was sore muscles, frustration and tears from being so upset by it. I have never experienced problems with sex or climaxing in the 14 years I've been with my husband. However, a couple of days before insertion, we had had sex and it was fabulous, as always. I climax every time we have sex, so it's been very upsetting.

I weighed myself today, just out of curiosity, and since the insertion, I've lost 7 lbs. I'm not dieting, not exercising, not even trying to lose any weight.

Upon calling my gyno and discussing my symptoms with her assistant, I was told that it couldn't be the Mirena, because the amount of hormones in it are so minute that they wouldn't affect anything outside of the uterus. I was told that something else in my life must be causing my sexual problems. !!! I don't think so! The IUD is the only thing that has changed in the past 2 weeks! And how do you explain a sudden loss of 7 lbs??? She didn't want to say it straight out, but she was trying to tell me it was all in my head.

I've had sex again since my failed attempts, and it's getting better, as is my appetite, so I'm hoping that my body is simply adjusting to the new IUD and getting used to the hormones. I have not been on any medication or hormones in the past two years, as I've been pregnant and then breastfeeding, so it might be quite a shock to my system.

If my inability to acheive climax continues, I am going ot have the IUD removed and have another copper IUD put in. My sex life isn't worth this.
