Should I get my IUD out?

Addie • 19 years old, sophomore at CCC, I love my fiancé 11-8-16
I have had the Mirena for 3 weeks now. My period has lasted 2 weeks and is still going, and my emotions are through the roof. Normally my emotions only go out of whack the week before my period, but my boyfriend says he's noticed I've been more distant and moody and aggressive, which I agree with. I hate not feeling like myself, I don't feel comfortable, and I have gained 10+ pounds since it started. Should I call to get it out? I kinda want to. I hate how I've felt these 3 weeks... Wish it could've gone better. I had no pain which is rare, but these symptoms are almost worse than the pain people experience.
