abnormal uterine bleeding
"Had Mirena inserted 4 weeks ago. Don't need it for BC, but I am extremely iron-deficient, so it was to stop my periods. 

Nevermind the actual procedure, I didn't take any pain killers before or after. But I have been bleeding and badly cramping ever since the procedure. Sometimes cramps would stop, then come back suddenly so bad I groan out loud. Any physical activity makes it much worse. My tum & breasts are swollen & tender. Some acne. Mood swings - more like mood plungers: I tend to snap at everyone around for no reason. Definitely a weight gain - 2kg in 4 weeks. Everyone says I look very pale. Total life disruption. I wish I read other reviews before doing it. My GP told me it would settle after 3-4 days. It comes out next week."
