Hi,

I've had both the copper and the mirena IUD. The copper IUD was OK on my hormones, but I bled heavier each month and doubled over with cramps at any given time of the month. Unfortunately it didn't work quite as well as I'd hoped - I got pregnant! Now, I'm on the mirena. I spottted every day for four months after it was inserted, but now I don't even have a period. I'm constantly tired though. I mean bone tired where I don't have energy for anything. My sex drive is still pretty high. In terms of a spontaneous birth control, nothing beats the IUD. It just comes down to your own personal decision.Hope I helped.

I had both I recently took the merina otu and tied my tubes. There is a big difference in the two. I personally like the copper better but after appr. three years it did not like me, I got pregnant. I did not like the merina, becasue my face broke out really bad and I could not lose weight as easily. However contiune to do your research and good luck.
