Levonorgestrel
"Got my first Mirena in 2012 after I had my first child. It was great for the first year, no bleeding no symptoms, perfect! About a year and a month in I started having yeast infections 2-3 times a month every month. I couldn't take it any more so I got it removed. After baby number 2 I figured I'd try it again and that I would take probiotics, eat yogurt and drink plenty of water. It worked. However after only having it in for a month I did bleed for a week but nothing since, but my sex drive is non existent. Me and my boyfriend use to be very sexually active, but no now I've never had this problem. we don't even try anymore and that's depressing."
