So my exp. with Mirena was HORRIBLE. I chose that IUD because my doc said the Paraguard was so bad, he refused to put it in anyone. (months of heavy bleeding and cramping) Insertion wasn't too bad. It did hurt, but was mostly like mild contractions. So I'm not really sure what the difference was with the Mirena because i bled for almost 3 months straight, very heavy bleeding at that. Once it finally slowed down to normal periods i was so relieved.
One day i was doing the monthly string check, and they weren't there... :-/ I called my doc and they said the strings were just tucked up in there and gave me an appt. for 2 weeks later. WELL, two weeks later, after an internal exam, internal AND external ultrasound AND being shipped to the hospital for an x-ray, the decided it was gone!!!! IT FELL OUT!!!!!! I never even saw the darn thing! The doctor said, " oh no worries, it's floating around in a toilet somewhere.." (I never had a problem with this OBGYN until now, actually loved them.... rethinking the "love" word at this point...)I had been walking around for weeks with no birth control!! No one told me that was a possibility when i had it put in, but i guess it is pretty rare. All the doctors seemed pretty amazed by me. It was great to feel like a science project. Make sure you know ALL the side effects and possible things that could go wrong before you get it.
We are now trying for baby number 2, and it's been about two months with no success yet. (Every time I've tried in the past i was PG within 2 weeks, but also had 2 miscarriages) Not sure if that has anything to do with the IUD though.
I've heard the NuvaRing is great, and that will be my next option when it is needed. My doc said that the hormones in things like IUDs and the ring don't really matter because they are mostly contained to the uterus. (Then again, why would i trust anything they say now??)Hope everything works out for you. Good luck!
