birth control reccommendations?

So, here it is 3 months post partum, and I'm just now starting to consider
my options for birth control. I was on depo before, but gained weight and
didn't care for the hassles of going in for an injection every 3 months. I
have always had super irregular cycles though, and with depo I had no period
at all... I liked that! But my doc says there are bone density issues
coming out now with depo, so I'm looking into other things. My doc is
suggesting an IUD, but I've heard bad things about that in the past, and
also wonder if you can feel it there? We are not planning on more children,
so I wish my husband would just get the procedure, but he seems pretty
reluctant to do anything permanent. Whatever I choose, I am assuming I will
still have irregular cycles, and wonder if the only treatment for that is
still taking the pill?

so many questions! and I'm still not even sure I'll ever want to have sex
again! lol...
