Mirena
"Inserted July '16 to control extremely heavy periods.  Insertion-tolerable with a day of cramping.  Within a week, I started having constant leakage-requiring a liner every day. Cycle 1-3 were lighter-but LONGER.  (10+days compared to 5-6 days)  I also started cramping, which I hadn't done since puberty.  The leakage NEVER stopped. I scheduled a removal because constant leaking and wearing a liner every single day wasn't something I could deal with anymore...feeling unclean made being intimate with my husband very difficult.  AND in 3 months I've gained 10 pounds. Sadly a family emergency required me to put off removal by a week.  This 4th cycle is a nightmare.  HEAVY bleeding with golf/ baseball clots. I wish I'd never had Mirena inserted."
