Levonorgestrel
"I've had this for 7 months now. I got it 8 weeks after I had my baby. The pain getting it inserted was very minor compared to the natural no med labor I had 8 weeks prior. My cycles were longer in the beginning and now I'm down to three days and wearing panty liners, that's how light it is. This IUD varies from person to person. I would recommend it to see how it works for you. Plus my insurance paid for it fully."
