I have been having brown spotting on and off for about 12 days now. About the time I started spotting I had some stronger cramps after a shower and felt the urge to push. I didn't have to go to the bathroom, nor did I when I pushed, but I felt a strong urge to push and I have never experienced that before. I have had nausea, fatigue, occasional mild cramping, swelling in my fingers, and some dizzy spells. I have had the mirena for over a year and a half now and can feel my strings. I returned from active duty deployment and did not have a period while I was gone or for the first few monts after returning home. I had a normal period around Thanksgiving in November, a period again in December around Christmas. My period was a week early in January although I can't remember the exact date. I took a home pregnancy test this morning and it was negative. I am supposed to have my IUD removed tomorrow and am unsure what I should do.
