Mirena and checkups

I have had the Mirena in me since August of 08 and the day they put it in I never received even a pamphlet. It took the doctor over 30 minutes to get it in me and he asked me if I still wanted it while he was having trouble putting it in. He was the doctor and he should have known.
I was never told to come back for checkups or anything just that it had to come out in 5 years. He told me of no side effects or anything. So thinking it was the best I had it put in. I cramped for 4 days after. I bled really bad and finally it went away. Well then just the past couple of months since my periods started getting lighter all my symptoms are getting worse.
My symptoms include : fatigue, stomach cramping so severe I can hardly walk, mood swings, depression, weight gain and constipation ,my feet go numb all the time and if I stand for a long time to, also have like a stabbing pain in my chest (rare) and Im beginning to not have any sex drive.

Calling the doctor tom to have it removed because I thought all this was in my head until I have researched it past the website.
