Hello!! I have had my mirena for six in a half years now. I have been having unprotected sex with my boyfriend for a few months now. The thing is I am having this pregnancy scare for a month and some weeks now. Of course I dont have a cycle because of the mirena. Within the past month I have some weight gain around the mid section area, soreness tenderness of the breasts, shortness of breath, now nauesa, flutter feelings in my abdomen, pressure of the abdomen especially underneath. My boyfriend thinks I am because I have been very moody and dealing with a lot of fatigue. I did take 2 pregnancy tests with in the month both came out negative. I do have two children who are 8 and 6 as well. with my first pregnancy i didnt know i was especting til i was 7 wks in. i took 4 tests then and all were negative. I did make me an obgyn appt just this morning for a well woman check up and hopefully they can remove the mirena...... has anyone else had these problems while on the mirena?
