I had mirena put in in November, as I was told it was the most effictive bc. I had my period November and December normally, and haven't had one since. I was told you can stop getting your period while taking mirena but I thought it took more time. I have never had a child, want one, but not at this time. My fiance and use this as the only form of bc. THe last month or so I've noticed fatigue, abdominal pain, constant nausea, breast tenderness and darkining, and even some vaginal distarge and spotting. I'm extremely nervous and have took a hpt this morning which was negaitive. What do I do??
