I'm glad I found this site. From the moment the Mirena was inserted, something was different about my body. It was inserted in October 2006 - 12 weeks after the birth of my twins. I thought it was a good idea until the side effects started. In November 2006, during a staff meeting, I felt an INCREDIBLE pain on the left side of my lower abdomen. I thought it was a one time occurrence, until I felt it again every month before my period was due. Then, during a routine check up with my primary care physician, he noticed that my blood pressure was extremely high (150/100). After monthly check-ups and blood pressure medication, it still hasn't resumed a normal range. I would have been able to manage these two side effects, but things got worse. In July 2007, I started to experience shortness of breath. To be honest, I have allergy asthma, but it didn't feel like a regular attack. So, I went to my pulmonologist for a check-up. He conducted the following test: breather-lizer (to check my breathing pattern), blood oxygen level (stationary & running up stairs), EKG, x-ray of my lungs, blood test and a CT scan of my lungs to see if I had blood clots. All the test came back negative!!!!! He answer - it's your birth control. Went back to my PCP to get my blood pressure checked, and it was still high. So, recommended that I get an Eco-cardiogram of my heart. Of course, it came back negative! Actually, my PCP said that I'm extremely healthy. However, the hormones in my birth control could be causing an adverse reaction to my system. Keep in mind ladies, I've gone to my OB to get the Mirena removed and her only concern is that I can't get pregnany any time soone because my twins are 12 months old and I had a c-section. So, my uterus won't completely healed until Januar 2008 (18 months post-partum). To finish briefly, I also have been having extruciating headaches; teenage acne; neck, shoulder & back pain; fatigue; and to top off the list - I have gained 25 pounds since the birth of the twins. In summary, I would not recommend this product to anyone - not even my worst enemy!!!! I'm going to call my OB again tomorrow to schedule an appointment to get it removed. If she refuses, my PCP said to call him and he'll strongly suggest that she take it out. If she refuses him, then he's going to send me to another physician at his affliate hospital that will handle this situation.
