I got my mirena about a year ago and ever since I have on and off had cramping in my lower back, hips, lower stomach and sometimes my leg. About a month or two after it was put in I had a check up and it was all fine and in place still. About 3 days ago I started bleeding with pains which felt how my old period pains felt and wondering if it's normal for irregular bleeding on mirena? I didn't bleed at all until the last few days and wondering if this is a period or something more sinister
