http://www.medications.com/effect/view/29110 I can't tell you how happy I was to find this web site. I had my Mirena inserted almost 2 years ago now. Was looking forward to having NO periods but that never happened...they're lighter but last longer. Some months I'll have spotting for a week or two Tue, 15 Apr 2008 02:20:16 -0400 http://www.medications.com/effect/view/29110?item=7222 I'm 19yrs. old and I had my IUD put in 5 1/2 months ago with the promise of no periods anymore, just as you had. So far I have also experienced lighter but MUCH longer periods with on and off spot bleeding all month. Also I seem to get cramps all the time http://www.medications.com/effect/view/29110?item=7222
