After my daughter was born almost 5 years ago, I chose to get the Paraguard IUD, because it does not contain any hormones. It uses copper, which is a more natural contraceptive. As my Dr explained to me, most IUD's involve heavier flow periods. I also found this to be the case. My average period was 9 days. I did have it checked regularly and never had any other complications from it. I had it removed a year ago and was pregnant 2 cycles later. So, I guess you could say I was happy with the overall effectiveness of it. It isn't the most convenient for lifestyle, but it does work.
