K.H.
I have the Mirena and yes I like it. They usually place it w/in 10 days of your period(according to my doc), not sure if it has to be while you're actually bleeding or not. I had cramping that first day (like light period cramps) and irregular periods for the first 6mo or so. I think it's a great form of bc, it's simple and hassle-free. Good luck!
