by lilylover » Jul 21, 2009 H''okay. Sorry if this is too much information, but I have to ask! Here is some background info: I am on the Mirena IUD. I have had it for over 2 years with little problems. My period started out July 1st with very little spotting... it didn''t really pick up until about 4 days later. I had my normal length period, with cramps, etc. then my flow lightened. I thought it was going to end like normal. BUT-- I have been randomly spotting off and on (but everyday) since then! It has been 3 weeks. Has this happened to anyone else? It''s super light, I don''t have any cramps or anything... but it is concerning me slightly. Thanks!
