Mirena is the most reviewed brand of hormonal coil or 'IUS' at The Lowdown. Like all hormonal coils it releases a low amount of progestogen into your womb, meaning low levels circulate through your system - this may be why most women experience few side effects. Plus many users have lighter bleeds or even no periods. Once it's fitted, the Mirena can stay in for up to 5 years.
