I had a mirena coil fitted in January this year, the fitting itself went well - only suffered slight discomfort when it was being attached apart from that I have had no problems. Every now and then particularly after exercise (not intercourse) I get lower abdominal pain it actually feels very similar to the discomfort i experienced when the coil was being fitted! It doesnt last for a long time but it is uncomfortable not painful. I went to get the coil checked at my local family planning clinic last week and everything was fine but again I am suffering with this uncomfortableness and I m wondering could I be suffering with a slight infection?
