HI J., I know this reply is really late and you have a bunch of posts already, but I thought if you hadnt decided yet, I would give you my 2 cents! My husband and I decided we were done having kids and he had a vasectomy. I was looking forward to letting my body get back to normal-after kids and breastfeeding etc, with no birth control. But, once I finished breastfeeding, my periods came back so strong and heavy that I was boarderline anemic. So, I have decided to get the Mirena IUD. So far I am happy with it. The funny thing is that my husband never had to have the vasectomy because now I am on a pretty good and long lasting birth control! The other day we were talking about this fact and he told me that he would tell any man he met who wanted to have a vasectomy not to do it. Im sure he would not be happy if I shared this, but he said it has changed him, and how he feels during those intimate times :) I would recommend you go with an IUD, its totally reversable, and easily managed. And, its nothing so drastic. Good luck to you! Enjoy your kids!
