"i&#039;ve had the mirena for about 2 years now and for me, it&#039;s really a trade-off. i need to be careful with my medication not to get pregnant without planning for it. so the mirena has been wonderfully effective in that regard. however, i can only rate the mirena how i do because the strings poke. they poke my husband during intercourse, they poke me. on the inside. like little needles. they also have caused my periods to turn into a 2 week long after-period discharge session. i also have seen no improvement in my hormonal symptoms. to me, it&#039;s a tradeoff."
