birth control
"I was very excited to try Mirena. I experienced the normal, cramping and extreme discomfort and pain immediately after placement. My cramping and pain lasted longer than normal.  Roughly 15 days after placement, I became intolerable.  It was the worst PMS I can recall ever having.  I wasn't that moody when I was pregnant.  Then my period came and it was the longest, most painful period I have ever had.  I went from having a 3-4 day period with one day of cramping to a week and a half period with 5-6 days of cramping.  Next month, same thing.  Needless to say, this is coming out."
