so I know this is gross, but it's very unusual. I got my Skyla IUD NOVEMBER 14th 2015. it's been more than 6 months and things still are unusual down there. I've been spotting like this for a long time, probably over a month and i finally stopped for about a week and now it's back again. had this happened to anyone else? is this normal or should I get checked? thank you guys in advance.
