i had my mirena IUD inserted about 5 months after i had my one and only child. I was very happy with my IUD. After the IUD I had very very light periods but they werent on a schedule but my period was so light it wasnt a problem...after 2 years of having my IUD i began to bleed heavy...for 13 days!!! plus i noticed a smell? so i checked my strings and they felt lower then usual so i went to my dr and she said the IUD was perfectly fine and the bleeding was prolly due to stress (and that it was old blood, hence the smell, blah) and that it isnt abnormal to all of a sudden have a heavy longer period once in a while, she gave me a prescription for the bleeding and i left thinking everyting was fine. 2 weeks later i started bleeding again and felt the strings and they were even lower and the smell was still there?? so i began to feel the strings and make sure they still went all the way up and into my cervix, i felt a light quick ouch and when i looked down my IUD was coming out!!! so of course i freaked out and called the dr and made an appt. and she called me in a prescription for what she called the "plan B" pill because i had had intercourse before the IUD came out. that was just a few days ago and since then ive stopped bleeding, i feel fine, and the smell is gone, yay! i think my body was trying to get the IUD out of my body, i just wonder why after 2 years?
