Yeast infectons symptoms and conditions

I have had the Mirena since Aug 2007. Since i have had this, I had gotten acne cysts, moodiness, and lack of sex drive. i though i just may still be having PMS without having my period, but now i'm thinking it's the implant. I also keep yeast infections and discharge due to too much hormones being absorbed. (my gyno said that sometimes it may look like a yeast infection whe if fact it is extra progesterone coming out) she gave me a very low dose of estrogen and it seemed to help) but recently i have started antibiotics for my acne which in turn gave me a yeast infection (joy joy). thinking about having it removed and going with nuvaring cause its actually costing me more money than what i'd be spending on the pill (dermatologist appointments, diflucan RX, acne meds) i think the cons are outweighing the pros at the moment. Has anyone else experienced yeast infections? i don't see anyone that has posted it yet.
