"i got the mirena after giving birth about 7 weeks post partum. i bleed terribly almost every day.  terrible back pains and no energy. sex went out the window. my doc said to give it three months to regulate but this sucks. i&#039;m bloated all the time and can&#039;t loose any weight. so far i&#039;m thinking its not worth it. obviously, its doing its job but this is not fun and its ruining my sex life !!  also been getting headaches that won&#039;t go away."
