Mirena
"I definitely can't say my experience with Mirena has been anything but crappy. The initial insertion of the IUD wasn't as bad as I imagined, didn't take more then 20 minutes. I was crampy for about a day and was already bleeding as I was on my period so I wouldn't have known the difference from spotting and my period. But its been over 4 months now n I'm still spotting. Mainly that brown end of the period kind of junk, can't really tell whats my actual period anymore. I do lighty bleed for a few days then it'll just go back to that brown spotting. Doctor said 3 months for spotting but the actual Mirena site said up to 6 months so well see here in a month or so. I don't know how much longer I'll keep it after 6 months..a year seems unlikely."
