I think every mom on mamasource knows how i feel out Mirena...just look at my past posts and responses about it My IUD fell out after about 6 months, and i didn't know for weeks.. I felt for the strings one day, and they were gone. I got the earliest appt. (2 weeks later) and had 2 ultrasounds (internal and external) and was sent to the hospital for an x-ray after the obgyn couldn't find it. Come to find out it was GONE!!! It feel out god knows how long before that, but i never saw it. I some how didn't become pregnant. Be careful to always be checking for those strings if you do get it. I had a lot of random bleeding for the first 3 months, and things finally settled down.. but..yea, then it fell out... Insertion wasn't too bad. Pretty much like a contraction while they put it in and cramping for a few hours after that. Good luck, just know ALL the risks before you get it.
