Birth control switch.

I have been on the pill for about two years. I haven't had a period since November. My doctor has been giving pregnancy tests via urine and blood and they all come back negative. So recently she asked me have I considered and IUD? I have had Mirena before, but I had contracted PID. I'm not going to let a bad experience from 9 years ago stop me from possibly getting my periods back, so I'm turning to help from my favorite, most helpful ladies. So help me out ladies, Skyla or Paraguard? What do you think? I'm trying to get my periods back and more regular.
