Mirena IUD pain

Megan
I've had my mirena for 3 days now and my pain is getting worse and worse. Too the point where I took an oxy and 800 mg ibuprofen and it didn't do a single thing to the pain. It's shooting up my spine and down my legs. Is this normal?! When I got it put in I threw up and passed out because it hurt so bad and I have a REALLY high pain tolerance.
