"i got mirena 6 weeks after my second child was born in hopes for easy birth control. insertion was painful, but nothing a little ibuprofen wouldn&#039;t handle. i bled very light for 6 weeks straight after insertion. finally my period came regularly it was extremely light but lasted at least 3 days longer than normal (7+days). that was nothing compared to the pain the iud caused me 24-7, my husband felt it, even 9 months into having it he moved it causing extreme nausea, dizziness, back pain for 2 weeks until it moved back to place. then lets add the severe pms symptoms to the mixture, i was miserable. had it removed 17 months after insertion and would not recommend to anyone. the pain and side effects out weight the benefits."
