I had a copper IUD inserted in mid July of this year, since then I have not had a period. I have however had constant spotting since the insertion, on most days I must wear a pantie liner and a couple times it seemed enough to wear a pad or tampon but then ended up not really necessary. I have had some PMS symptoms a few times, like some cramps, stronger appetite, emotional sensitivity, but again this has only been a few times. I don't know whats going on, I have read things that have said this is no big deal and things that are really scary. HELP!
