abnormal uterine bleeding
"I had copper T before having  Mirena inserted. With the Copper T I had the worst experience of abnormal bleeding, cramping and lower abdominal pain for 3 months.  My gyno advised me to switch to Mirena. After reviewing a lot I decided I should give it a try and it was inserted on 19th Feb 2016, since then a little cramping and bleeding but not heavy.  I'm still waiting at least for a month to see if things works for me.
Anyone can give it a try women bodies are different after all."
