My daughter had mirena IUD (not sure of spelling) put in, 2 months after delivery of her baby, around Feb 17, 2015. She has been having a lot of pain and discomfort quite often, especially after sexual intercourse. Also, she has had a continuous period since delivery of her baby. Her OB GYN did an ultrasound and said the mirena had moved and is now located in the middle of the uterus instead of towards the top of the canal, but said that was still okay. Her doctor doesn't seem to know why she is having a continuous period or why she is having pain, mainly on the left lower abdomen and after sexual intercourse.
