"i first would like to thank all of you that posted comments. after reading them, i felt i&#039;m not alone. it&#039;s not just happening to me, there is nothing wrong with me. i&#039;m 34, with one child and had mirena for 5 months. the insertion was almost painless and the first month was fine. right now, i have gained 10lbs, loss of sex drive, have headaches, back pain, insomnia, constipation, hair loss and general depression - of course that&#039;s going to cause to have mood swings. i&#039;m waiting on an appointment to have it removed. another important aspect is that i had suffered from postpartum depression after the birth of my child 4 years ago and honestly i was worried that these side effects (especially  depression) were a sign that i was still not okay."
