I have had a missed period and have been getting cramps and sore breast. I had the IUD removed in October of 2010 and I tired to start birth control in December but doctor and I decided to just give my body a rest and start them up in couple months. I had a period in January and a period in February but March didn't have one. All I had was white discharge and cramps. Today I had a jelly like substance that was light brown when I whipped. I took two pregnancy tests that came out negative. Does this mean I am having hormone problems since I still haven't had a period or is this caused by the IUD? Please help!
