"wasn&#039;t too bad to insert. first 3 months i had continuous spotting. period stopped after 3 months. at first it felt fine.. developed gad and anxiety disorders half a year in and started crying for no reason at everything and had to see a therapist twice. i thought it was just me going crazy until a year passed and i got my period all of a sudden. my monthly periods then would last 10-12 days and hurt like hell. cramping was unbearable. i never cramped on bc pills or off bc pills, but all the time on mirena. i was depressed, tired, gained 10lb and was always hungry, anxious 24/7, and sensitive to every little thing. removed my iud after a year and a half of use and switched back to bc. very disappointed with this- i had such high hopes"
