S.L.
There are 2 types- 1 with hormones-Mirena, 1 without-Paraguard. I have had both. I had the Mirena for 3.5 years. I loved it while I had it the 1st few years. Due to the hormones I only had like 1 period a year, never spotted inbetween either. Then for a few months I begen bleeding every other week, and felt horrible. I had an ultra sound and it had fallen out of place, and the hormones were really messing with me. I constantly felt irritated and was moody all the time. I didn't really notice those feeling until I had it removed. The same day I had it removed, I had the paraguard put in. I have had it since August. I had a period every 30 days until last month. And I felt wonderful being off the hormones, I'm not irritaed all the time and more loving and affectionate. In Nov. I was late, had some spotting and a huge clot. Didn't have anything for Dec. and started on the 1st. My cramps are alot worse and my bleeding is very very heavy with this one.
All in all I love them just due to the fact you don't have to worry about them for years at a time. I can't feel that it is in there, my hubby can't feel it either. Like anything else it does have serious complications and health risk. You can go to there main sites and read up on the complications. Good luck with your decision!!
