abnormal uterine bleeding
"Had the Mirena in for a month and first period is basically non-existent.  Was recommended for by my gynecologist because of harsh periods and excessive bleeding causing iron deficiency, though I don't really think my bleeding was that excessive. Have had minimal cramping and hardly any discharge, no bleeding to speak of.  I was worried coming off the pill that my acne would come back, but my face is clearer than ever.  Have noticed some abdominal bloating, but its only the first month so not a big deal.

HOWEVER...people should be warned about the insertion process as it was quite a terrible experience even with a very gentle and experienced Gyno.  Frankly, it hurt bad and I had immediate cramping. Have a driver with you."
