I'm not sure hun. The pain from the mirena only lasted a few hours for me, but I had a D&C a long time ago and I remember being in pain for a few days from that. If it lasts longer than a week I would talk to your doctor. As for the bleeding, that could last a few weeks after having the mirena put it - and it can be start stop also. But if you are at all worried, talk to your doctor, peace of mind is really important.
