birth control
"I'm 37 with no children and have had mine for 5 years.  I was having really bad abdominal cramps/diarrhea while taking oral contraceptives which went away when I stopped taking it, wanting an effective contraceptive I figured I would try mirena. The insertion was rather painful - I got all hot and watery mouthed, thought I was going to throw up, the cramping and spotting lasted about a week. My periods got lighter each month until they stopped completely - so wonderful. I am due for replacement this month, I started spotting about 4 months ago which seems to time with a monthly cycle, I am assuming this is as the medication is wearing off."
