I had the Mirena placed about 7-8 months ago.... my periods had been normal till now. I have been spotting for over a week and today I finally thought it went away.... so my fiancé and I intercoursed and now I'm spotting again... is this something to be concerned about with the Mirena!? Please help... thanks
