I got Mirena beginning of August 2011 it is now jan2012. In the last week I have felt pregnant. Ism officially not prey. Blood test and u/s! Nausea headaches weakness light headedness. Everything I ever did pregnant. I am now on high blood pressure meds at age 21. In stage 1 for heart disease. I eat generally good. I'm wondering if anyone felt like this and if they chose to keep it or get rid of it and if you kept it did they go away and about howlong?
