1 Month: Mirena IUD

Hey all, I'm approaching 1 month with the Mirena iud. I'm generally positive about my experience thus far but want to share a few specific issues.
1) contractions -- these suckers are heavy, debilitating and random. They are unlike mild period cramps. Deep breathing and relaxation help as they subside. I believe this is my body rejecting the device and fervently trying to push it out.
2) spotting -- nearly every day. Very very light, but there. Cautiously avoiding my nice underwear.
3) hair loss -- this I am on the fence about and very worried. I have noticed a signicant amount of hair loss and am going to follow this closely.
