Mirena
"I have had 3 kids all via c-section and had Mirena inserted over 2 months ago.  For me personally, insertion was not painful at all.  The thing they use to open me up during pap smears was the thing I felt most.  I didn't use any medication before or after insertion.  I didn't have any cramping after insertion either.  So far I still have irregular bleeding/spotting.  I'm hoping that goes away soon since it's been over 2 months.  I have noticed an increase in hair loss, but I can't be certain it's from Mirena or from a stressful move to a new very hot & humid state.  I haven't had any mood swings, depression, or acne like others have stated.  So far I'm pleased with it.  And hopefully my bleeding will stop soon so I can rate it a "10"!"
