"i have had mirena for a little over a year now, got it about 8 weeks after my daughter was born. since i was already prone to ovarian cysts and it&#039;s a possible side effect, they are worse now. i used to have a very high libido and now i could care less. honestly i can&#039;t even get in the mood.  i have no interest what-so-ever in sex. it seems as though i am still as moody as i was when i was pregnant. lately i have been getting sick frequently not sure if there is any relation. but besides that i love my mirena, can they just make a low estrogen one? that would be great!"
