Quoting D'Raes Mommy[;:" I have that IUD and I just had my first period with this IUD. But its not even a period I keep spotting, ... [snip!] ... in my vaginal canal but it feels like stabbing pain not cramps, but really painful. Anyone ever had this happen and know why???"I spotted like that for 3 months. And sometimes I get horrible cramps like what you're having. Not sure why either, haven't had it for a month or so. If I get them again I'm getting it pulled out.
